Abstract

A display includes: a plate member having flexibility and including a first face and a second face that face each other; a frame member provided on the first face of the plate member and extending in one direction of the first face; and a display body having flexibility and disposed on a side of the plate member on which the second face is provided.

Claims

1. A display, comprising:

a plate member having flexibility and including a first face and a second face that face each other;

a plurality of frame members, each frame member provided on the first face of the plate member and extending in a first direction of the first face; and

a liquid crystal panel having a light source, a heat releasing plate, an optical sheet, a light guide plate and a reflection plate, said liquid crystal panel having flexibility and disposed on a side of the plate member on which the second face is provided,

the plurality of frame members include a first frame member arranged at an upper side of the plate member, a second frame member arranged at a lower side of the plate member, and a third frame member arranged at an intermediate location between the upper side of the plate member and the lower side of the plate member,

the plate member includes a protrusion extending in a second direction which is orthogonal to the first direction, said protrusion having a recessed portion located between the second face of the plate member and the liquid crystal panel,

the plate member having a first end and a second end located at opposite ends of the plate member in the first direction, and said protrusion being provided at a location other than the first end or the second end, and

the heat releasing plate (i) arranged within the recessed portion of said protrusion and configured to extend in the second direction and (ii) configured to dissipate heat generated by the light source and to provide structural reinforcement for the plate member.

2. The display according to claim 1, wherein

the plate member has a shape, in the first direction of the frame members, same as a shape of one of a side and a face of the frame members, the side and the face of the frame members facing the plate member, and

the liquid crystal panel has a shape same as the shape of the plate member.

3. The display according to claim 2, wherein one of the side and the face of the frame members facing the plate member is curved in part or in whole in the first direction of the frame members.

4. The display according to claim 3, wherein one of the side and the face of the frame members facing the plate member has locally-different curvatures in the first direction of the frame members.

5. The display according to claim 2, wherein one of the side and the face of the frame members facing the plate member has a shape of a part of a polygon in the first direction of the frame members.

6. The display according to claim 1, wherein the plate member includes a plurality of second protrusions disposed in parallel to each other, the second protrusions being arrayed in the first direction of the frame members and each extending in the second direction.

7. The display according to claim 1, wherein the plate member includes another protrusion extending in the second direction and having the recessed portion located between the second face of the plate member and the liquid crystal panel, and wherein the liquid crystal panel has another heat releasing plate which is arranged within the recessed portion of the another protrusion and configured to extend in the second direction, to dissipate the heat generated by the light source, and to provide structural reinforcement for the plate member.

8. The display according to claim 7, wherein the another protrusion is provided at the first end or the second end of the plate member.

9. The display according to claim 1, wherein the protrusion is provided at a center of the plate member between the first end and the second end of the plate member.

10. A display comprising:

a liquid crystal panel assembly having a light source, a heat releasing plate, a liquid crystal cell, an optical sheet, a light guide plate and a reflection plate, said liquid crystal panel assembly having a display side for viewing images which substantially extends in an up-down direction and a right-left direction, and said liquid crystal panel assembly having a curved shape in a plane defined by the right-left direction and a thickness direction, in which the up-down direction, the right-left direction and the thickness direction are orthogonal to each other;

a plate member having a front face and a back face, said plate member being separate from the liquid crystal panel assembly and having the curved shape of the liquid crystal panel assembly; and

a plurality of frame members, each frame member provided on the back face of the plate member and extending in the right-left direction;

the liquid crystal panel assembly being disposed on the front face of the plate member, and

the plurality of frame members include a first frame member arranged at an upper portion in the up-down direction of the back face of the plate member, a second frame member arranged at a lower portion in the up-down direction of the back face of the plate member, and a third frame member arranged at an intermediate location in the up-down direction between the upper portion and the lower portion of the back face of the plate member,

the plate member includes a protrusion extending in the up-down direction, said protrusion having a recessed portion located between the front face of the plate member and the liquid crystal panel assembly,

the plate member having a first end and a second end located at opposite ends of the plate member in the first direction, and said protrusion being provided at a location other than the first end or the second end, and

the heat releasing plate (i) arranged within the recessed portion of said protrusion and configured to extend in the up-down direction and (ii) configured to dissipate heat generated by the light source and to provide structural reinforcement for the plate member.

11. The display according to claim 10, in which the liquid crystal cell, the optical sheet, the light guide plate and the reflection plate of the liquid crystal panel are arranged in this order in the thickness direction.

12. The display according to claim 11, in which the reflection plate of the liquid crystal panel is disposed on the front face of the plate member.
