Abstract

A back side polarizing plate adhered to a back side glass plate is formed into an extension region of a region where a right side glass plate and the back side glass plate do not overlap with each other. A liquid crystal display module is fixed to a light guide plate of a liquid crystal display back-lighting module by adhering a first region which is an outer periphery of a liquid crystal display and a second region which corresponds to the extension region of the back side polarizing plate to each other using double-faced adhesive tape. The double-faced adhesive tape is made up of a black PET (Polyethylene terephtalate) base material or a like having light blocking properties, and two adhesive layers formed respectively on both side surfaces of said black PET base material or the like.

Claims

1. A liquid crystal display supporting structure comprising an overlapping region where two glass plates opposite to each other making up a liquid crystal display overlap with each other and a non-overlapping region where one of said two glass plates do not overlap with an another of said two glass plates, and adhering and fixing a liquid crystal display module of a COG (chip on glass) construction on which a driver for driving said liquid crystal is mounted in said non-overlapping region to a liquid crystal display back-lighting module having a light source and a light guide member which guides light emitted from said light source to said liquid crystal,

wherein a polarizing plate is provided over both said overlapping region and said non-overlapping region of said one of said two glass plates where said driver is mounted, so that part of said polarizing plate that exists in said non-overlapping region is used as an adhered/fixed face at which said liquid crystal display module is adhered and fixed to said liquid crystal display back-lighting module.

2. The liquid crystal display supporting structure according to claim 1, wherein part of said polarizing plate that exists in said non-overlapping region is used as at least one part of an adhered/fixed face at which said liquid crystal display module is adhered and fixed to said liquid crystal display back-lighting module.

3. The liquid crystal display supporting structure according to claim 2, wherein an outer periphery of said polarizing plate corresponding to an outer periphery of said said overlapping region is used as at an other part of an adhered/fixed face at which said liquid crystal display module is adhered and fixed to said liquid crystal display back-lighting module.

4. The liquid crystal display supporting structure according to claim 1, wherein said polarizing plate of said liquid crystal display module is adhered and fixed to said liquid crystal display back-lighting module using double-faced adhesive tape having light-blocking properties.

5. A liquid crystal display supporting structure comprising an overlapping region where two glass plates opposite to each other making up a liquid crystal display overlap with said each other and a non-overlapping region where one of said two glass plates do not overlap with an another of said two glass plates, and adhering and fixing a liquid crystal display module of a COG (chip on glass) construction on which a driver for driving said liquid crystal display is mounted in said non-overlapping region to a liquid crystal display back-lighting module having a light source and a light guide member which guides light emitted from said light source to said liquid crystal display,

wherein a plate member having roughly a same thickness as a polarizing plate provided in said overlapping region is provided in said non-overlapping region of said one of said two glass plates, so that said plate member is used as an adhered/fixed face at which said liquid crystal display module is adhered and fixed to said liquid crystal display back-lighting module.

6. The liquid crystal display supporting structure according to claim 5, wherein said plate member is used as at least one part of an adhered/fixed face at which said liquid crystal display module is adhered and fixed to said liquid crystal display back-lighting module.

7. The liquid crystal display supporting structure according to claim 5, wherein an outer periphery of said polarizing plate corresponding to an outer periphery of said overlapping region is used as at an other part of an adhered/fixed face at which said liquid crystal display module is adhered and fixed to said liquid crystal display back-lighting module.

8. The liquid crystal display supporting structure according to claim 5, wherein said polarizing plate and said member of said LCD module are adhered and fixed to said liquid crystal display back-lighting module using double-faced adhesive tape having light-blocking properties.

9. A liquid crystal display supporting structure comprising an overlapping region where two glass plates opposite to each other making up a liquid crystal display overlap with each other and non-overlapping regions where said two glass plates do not overlap with each other, and adhering and fixing a liquid crystal display module of a COG (chip on glass) construction on which a driver for driving said liquid crystal is mounted in at least one of said non-overlapping regions to a liquid crystal display back-lighting module having a light source and a light guide member which guides light emitted from said light source to said liquid crystal,

wherein a polarizing plate is provided over both said overlapping region and the non-overlapping region of one of said two glass plates, so that part of said polarizing plate that exists in said non-overlapping region is used as an adhered/fixed face at which said liquid crystal display module is adhered and fixed to said liquid crystal display back-lighting module.

10. The liquid crystal display supporting structure according to claim 9, wherein part of said polarizing plate that exists in said non-overlapping region is used as at least one part of an adhered/fixed face at which said liquid crystal display module is adhered and fixed to said liquid crystal display back-lighting module.

11. The liquid crystal display supporting structure according to claim 9, wherein an outer periphery of said polarizing plate corresponding to an outer periphery of said overlapping region is used as at an other part of an adhered/fixed face at which said liquid crystal display module is adhered and fixed to said liquid crystal display back-lighting module.

12. The liquid crystal display supporting structure according to claim 9, wherein said polarizing plate of said liquid crystal display module is adhered and fixed to said liquid crystal display back-lighting module using double-faced adhesive tape having light-blocking properties.

13. A liquid crystal display supporting structure comprising an overlapping region where two glass plates opposite to each other making up a liquid crystal display overlap with said each other and non-overlapping regions where said two glass plates do not overlap with each other, and adhering and fixing a liquid crystal display module of a COG (chip on glass) construction on which a driver for driving said liquid crystal display is mounted in at least one of said non-overlapping regions to a liquid crystal display back-lighting module having a light source and a light guide member which guides light emitted from said light source to said liquid crystal display,

wherein a plate member having roughly a same thickness as a polarizing plate provided in said overlapping region is provided in the non-overlapping region of one of said two glass plates, so that said plate member is used as an adhered/fixed face at which said liquid crystal display module is adhered and fixed to said liquid crystal display back-lighting module.

14. The liquid crystal display supporting structure according to claim 13, wherein said plate member is used as at least one part of an adhered/fixed face at which said liquid crystal display module is adhered and fixed to said liquid crystal display back-lighting module.
