Abstract

Disclosed is a liquid crystal display having a housing; and a liquid crystal panel which has a first substrate and a second substrate each of which has a nearly line-symmetrical and planar form and which have a nearly equal surface area and at least one of which are transparent, the first substrate and second substrate being nearly parallel disposed sandwiching a liquid crystal composition layer. The first substrate is provided with mounting end regions that are extended outside from the end of the second substrate at the line-symmetrical position of the first substrate, so that the liquid crystal panel is fixed to the housing through the mounting end regions.

Claims

1. A liquid crystal display, comprising:

a housing; and

a liquid crystal panel which comprises a first substrate, a second substrate and a liquid crystal composition layer,

said first substrate and said second substrate partially overlapping and sandwiching said liquid crystal composition layer to provide a display section;

said first substrate having mounting end regions that are extended outside from the end of said second substrate, said liquid crystal panel being fixed to said housing by said mounting end regions,

said mounting end regions being composed of only, and integral with, the first substrate,

said mounting end regions of said first substrate having a rigidity lower than that of the portion of said liquid crystal panel where said first and second substrates overlap, and external stress to the entire liquid crystal display panel is absorbed by deformation of said mounting end regions of said first substrate.

2. A liquid crystal display, according to claim 1, wherein:

said first substrate and second substrate have a rectangular form.

3. A liquid crystal display, according to claim 1, wherein:

said second substrate is of transparent material and is disposed at the display side of said liquid crystal panel.

4. A liquid crystal display, according to claim 1, wherein:

said first substrate and second substrate are of transparent material.

5. A liquid crystal display, according to claim 1, wherein:

said liquid crystal panel is fixed to said housing with an adhesive means disposed sandwiched between said mounting end regions and said housing.

6. A liquid crystal display, according to claim 1, wherein:

said first substrate is provided at two opposite sides with mounting end regions that are extended outside from ends of said second substrate, and

said liquid crystal panel is fixed to said housing through said mounting end regions at said two opposite sides, while a gap is provided between said first substrate and said housing at two other opposite sides.

7. A liquid crystal display, according to claim 6, wherein:

said adhesive means is double-sided adhesive tapes or adhesive agent.

8. A liquid crystal display, according to claim 6, wherein:

said gap is 0.3 to 1 mm.

9. The liquid crystal display according to claim 1, wherein:

said housing has a hollow part on its upper surface corresponding to said display section.
