Abstract

A display device includes a display panel having a front surface and a back surface, a first and second frame, a first elastic member arranged between the first frame and the front surface of the display panel, and a second elastic member arranged between the second frame and the back surface of the display panel, the second elastic member extending in parallel to the first elastic member. A hardness of the first elastic member varies along an elongated direction of the first elastic member so as to have a high-hardness portion, and wherein a hardness of a first portion of the second elastic member which corresponds in location to the high-hardness portion of the first elastic member has a low hardness, a hardness of a second portion of the second elastic member which corresponds in location to the low-harness portion of the first elastic member has a high hardness.

Claims (18)

1. A display device comprising:

a display panel having a front surface and a back surface;

a first frame and a second frame;

a first elastic member arranged between the first frame and the front surface of the display panel; and

a second elastic member arranged between the second frame and the back surface of the display panel, and the second elastic member extending in parallel to the first elastic member;

wherein a hardness of the first elastic member varies along an elongated direction of the first elastic member so as to have a high-hardness portion; and

wherein a hardness of a first portion of the second elastic member which corresponds in location to the high-hardness portion of the first elastic member has a low-hardness, and a hardness of a second portion of the second elastic member which corresponds in location to the low-hardness portion of the first elastic member has a high-hardness.

2. A display device according to claim 1 , wherein each of the first elastic member has a center portion and an end portion along the elongated direction, and a hardness of the center portion and a hardness of the end portion are different.

3. A display device according to claim 1 , wherein a hardness of the first elastic member and a hardness of the second elastic member at a corner portion of the peripheral portion of the display panel are substantially equal.

4. A display device comprising:

a display panel having a front surface and a back surface;

a first frame and a second frame;

a first elastic member arranged between the first frame and the front surface of the display panel; and

a second elastic member arranged between the second frame and the back surface of the display panel and the second elastic member extending in parallel to the first elastic member;

wherein a width of the first elastic member varies along an elongated direction of the first elastic member; and

wherein a width of a first portion of the second elastic member which corresponds in location to the wide portion of the first elastic member has a narrow width, and a width of a second portion of the second elastic member which corresponds in location to the narrow portion of the first elastic member has a wide width.

5. A display device according to claim 4 , wherein each of the first elastic member and the second elastic member has a center portion and an end portion along the elongated direction, and a width of the center portion of the peripheral portion of the display panel are substantially equal.

6. A display device according to claim 4 , wherein a width of the first elastic member and a width of the second elastic member at a corner portion of the peripheral portion of the display panel are substantially equal.
