Abstract

An object of the invention is to facilitate attachment of a spacer to a support member in an assembling process of a liquid crystal display device. A display device includes: a display panel, a support member that supports the display panel and a spacer that is interposed between a cut end surface of the display panel and a first surface of the support member, the first surface facing the cut end surface of the display panel. The support member has a recess that opens through the first surface and a second surface, which is connected to the first surface and extends away from the display panel. The spacer includes a spacer position securing portion inserted in the space of the recess of the support member and a buffer portion that is integral with the spacer position securing portion and protrudes from the open end at the first surface of the support member toward the cut end surface of the display panel.

Claims (23)

1. A display device comprising:

a display panel;

a support member that supports the display panel; and

at least one spacer that is interposed between a cut end surface of the display panel and a first surface of the support member, the first surface facing the cut end surface of the display panel;

wherein the support member has a recess with an open end that opens through the first surface and a second surface, the second surface being connected to the first surface and extending in parallel to a display surface of the display panel;

wherein the spacer includes a spacer position securing portion inserted in the space of the recess of the support member and a buffer portion that is integral with the spacer position securing portion and protrudes from the open end at the first surface of the support member toward the cut end surface of the display panel;

wherein the spacer is made of an elastic material;

wherein a plurality of the spacers are provided; and

wherein at least one of the spacers of the plurality of spacers has a modulus of elasticity different from a modulus of elasticity of an other of the spacer of the plurality of spacers.

2. The display device according to claim 1 , wherein the recess of the support member is configured such that the area of the open end at the second surface is equal to or greater than an area of the external shape of the spacer position securing portion at a surface parallel to the second surface.

3. The display device according to claim 1 , wherein the spacer position securing portion has a portion whose width in an direction parallel to the first and second surfaces of the support member is wider than a width of the open end at the first surface.

4. A display device comprising:

a display panel;

a support member that supports the display panel;

at least one spacer that is interposed between a cut end surface of the display panel and a first surface of the support member, the first surface facing the cut end surface of the display panel; and

a frame member that covers the support member and a peripheral portion of the display surface of the display panel;

wherein the support member has a recess with an open end that opens through the first surface and a second surface, the second surface being connected to the first surface and extending in parallel to the display surface of the display panel;

wherein the at least one spacer includes a spacer position securing portion inserted in the space of the recess of the support member and a buffer portion that is integral with the spacer position securing portion and protrudes from the open end at the first surface of the support member toward the cut end surface of the display panel;

wherein the spacer position securing portion has an inclined surface that on a side of the frame member; and

wherein the frame member has a projection that is disposed on a surface opposite to and parallel to the second surface of the support member and in an area corresponding to the recess of the support member such that the projection is in contact with the inclined surface of the spacer position securing portion.

5. The display device according to claim 4 , wherein the at least one spacer is made of an elastic material.

6. The display device according to claim 5 , wherein a plurality of the spacers are provided and at least one of the spacers of the plurality of spacers has a modulus of elasticity different from a modulus of elasticity of an other of the spacers of the plurality of spacers.

7. The display device according to claim 1 or 4 , wherein the display panel is a liquid crystal display panel.
