Abstract

A fixing method where no dead space occurs when a liquid crystal panel is fixed to the main body cover of a liquid crystal display unit, enhancing mechanical fixing strength with relatively simpler structure. The present invention is directed to a liquid crystal display unit comprising a liquid crystal panel with a display portion and a plurality of side surfaces mounted thereon through a support body fixed to a main body cover. The liquid crystal panel is provided with a plurality of protrusions on each of the plurality of side surfaces. The protrusions each have a flat surface. A plurality of spaces are each provided between the flat surface and the side surface. The support body is fitted into the spaces formed in the liquid crystal panel.

Claims

1. A liquid crystal panel having a fixing mechanism, the liquid crystal panel comprising:

a display portion having a plurality of side surfaces along a perimeter of said display portion;

said plurality of side surfaces each including a protruded portion and a non-protruded portion;

said protruded portion having a flat surface; and

a slit formed between said protruded portion and said non-protruded portion.

2. The liquid crystal panel as claimed in claim 1, wherein said protruded portion comprises a plurality of protruded portions for one or more of said side surfaces.

3. The liquid crystal panel as claimed in claim 1, wherein said protruded portion is formed integrally with said side surface.

4. A liquid crystal panel comprising:

a display portion; and

a plurality of side surfaces along a perimeter of said display portion, said plurality of side surfaces each having a protrusion;

wherein said protrusion has a flat surface and a space is provided between said flat surface and the side surface, and wherein said flat surface of said protrusion has a recess.

5. The liquid crystal panel as set forth in claim 4, wherein said recess is a through hole.

6. The liquid crystal panel as set forth in claim 5, wherein said through hole is a screw hole.

7. A liquid crystal display unit comprising:

a liquid crystal panel with a display portion and a plurality of side surfaces mounted thereon through a support body fixed to a main body cover;

wherein;

said liquid crystal panel is provided with a plurality of protrusions on each of said plurality of side surfaces;

said plurality of protrusions each have a flat surface;

a plurality of spaces are each provided between said flat surface and said side surface; and

said support body is fitted into said spaces formed in said liquid crystal panel.

8. The liquid crystal display unit as set forth in claim 7, wherein a recess is provided in said flat surface so that it is engageable with a protruding portion provided on said support body.

9. The liquid crystal display unit as set forth in claim 7, wherein said flat surface is provided with a through hole.

10. The liquid crystal display unit as set forth in claim 9, wherein said through hole is a screw hole.

11. The liquid crystal display unit as set forth in claim 7, wherein said support body has a first flat surface and a second flat surface, the first flat surface being fixed to said main body cover of said liquid crystal display unit and the second flat surface being fitted into said spaces formed in said liquid crystal panel.

12. The liquid crystal display unit as set forth in claim 11, wherein said support body is formed into an L-shaped structure where said first and second flat surfaces contact each other at nearly right angles.

13. The liquid crystal display unit as set forth in claim 10, wherein said first flat surface extends from said second flat surface in an inward direction of said liquid crystal panel.
