Abstract

A liquid crystal display panel part group composed of a plurality of panel parts such as an array cell, a optical system sheet family, a light guide plate, a lamp reflector, and a lamp, and a liquid crystal display panel is enveloped in a film for laminating the parts. This film may be provided so as to cover the whole of the liquid crystal display panel part group and the film may have an opening. In order to adjust the positions of the parts, convex and concave portions are provided in the liquid crystal display panel parts.

Claims

1. A liquid crystal display panel comprising:

a liquid crystal display panel part group composed of stack of a plurality of liquid crystal display panel parts; and

a thin flexible plastic film envelope with an opening which envelope is wrapped around the display panel group is laminated onto exposed surface of top and bottom parts in the stack of the parts of said liquid crystal display panel part group to hold the stack of parts together during use in an operating liquid crystal display wherein said plurality of liquid crystal display panel parts comprise an array cell, an optical system sheet family, a light guide plate, a lamp reflector and a lamp.

2. The liquid crystal display panel according to claim 1, wherein said film is laminated on said liquid crystal display panel part group entirely.

3. The liquid crystal display panel according to claim 1, wherein said opening is provided at a position corresponding to an image display portion of said liquid crystal display panel.

4. The liquid crystal display panel according to claim 3, wherein said film is a light shielding film.

5. The liquid crystal display panel according to claim 1, wherein said opening is an opening for supplying a power source, a ground and an electric signal between said liquid crystal display panel part group and an outside thereof.

6. The liquid crystal display panel according to claim 1, wherein said liquid crystal display panel part group further comprises a protection plate.

7. The liquid crystal display panel according to claim 1, wherein said liquid crystal display panel group has a through hole.

8. The liquid crystal display panel according to claim 7, wherein said through hole is provided at a position of the film corresponding to a periphery of said liquid crystal display panel part group.

9. The liquid crystal display panel according to claim 1, wherein at least more than part among said plurality of the liquid crystal display panel parts have a positioning portion.

10. The liquid crystal display panel according to claim 9, said liquid crystal display panel further comprising positioning parts that mate with the positioning portion to hold the panel parts together, aligned with their operative positions.

11. The liquid crystal display panel according to claim 10, wherein said film is a plastic film.

12. The liquid crystal display panel of claim 10, wherein the position portions are notches in at least two of the liquid crystal display parts and the mating positioning portions are tabs attached to a liquid crystal display part between the two liquid crystal display parts.

13. The liquid crystal display panel of claim 1, wherein the film possess an adhesive property to laminate the film on the parts.

14. The liquid crystal display panel of claim 13, wherein said film has a stickiness either at room temperature or in a state where it melts by heating.

15. A liquid crystal display device comprising:

a liquid crystal display panel part group stack including a plurality of liquid crystal display panel parts one of which is an array cell;

a film pouch enveloping the liquid display panel part group within the enclosure and laminated to opposite sides of said liquid crystal display panel part group stack including the array cell to hold the parts of the liquid crystal display part group together in their operable configuration which laminated film pouch has an opening for viewing a display surface of the array cell; and

a computer unit cover.

16. The liquid crystal display device according to claim 15, wherein said film is screwed to said unit cover.

17. The liquid crystal display device according to claim 15, wherein said plurality of liquid crystal display panel parts in said group includes an optical system sheet family, a light guide plate, a lamp reflector and a lamp.

18. The liquid crystal display device of claim 15, including the liquid crystal pouch having tabs containing holes for attachment to the computer unit cover.

19. A liquid crystal display panel comprising:

a liquid crystal display panel part group composed of a stack of a plurality of liquid crystal display panel parts wherein said plurality of liquid crystal display panel parts includes an array cell, an optical system sheet family, a light guide plate, a lamp reflector;

an element containing parts and wires and a lamp; and

a film pouch enveloping all the parts of the stack of said liquid crystal display panel part group and adhering to opposite exposed surfaces at the back and front of the stack of the end parts of the group to hold the parts of the group together during use in a display unit.

20. The liquid crystal display panel according to claim 19, wherein said film pouch is made of a light shielding film and has an opening therein aligned with the image display portion of the liquid crystal display panel.

21. The liquid crystal display panel according to claim 20, wherein said pouch has a second opening for supplying a power ground and electric signal connections between said liquid crystal display panel part group in the pouch and the outside thereof.

22. The liquid crystal display panel according to claim 21, wherein said liquid crystal display panel group and the pouch have through holes to attach the group the rest of the display unit.

23. The liquid crystal display panel according to claim 22, wherein among said plurality of the liquid crystal display panel parts have positioning portions for alignment of the parts in their operative positions prior to their being held in place by adherence to the pouch.

24. The liquid crystal display panel of claim 23 including a peripheral metal protection plate between the element containing parts and wires and the plastic pouch to disperse heat and pressure to protect the element.
