Abstract

A display device according to the present invention includes a liquid crystal panel having a display area on which an image is displayed, and a peripheral edge area around the display area, a frame disposed in back of the liquid crystal panel, and first and second elastic members disposed at positions corresponding to the peripheral edge area of the frame, and having a bonding surface on which an adhesive member is provided. A portion of the first elastic member and a portion of the second elastic member are disposed on the frame to overlap each other, the bonding surface of the first elastic member has a first area overlapping the second elastic member, and a second area overlapping the frame at a position near a center of the first elastic member relative to the first area, and the adhesive member is divided between the first area and the second area.

Claims

1. A display device comprising:

a display panel having a display area on which an image is displayed, and a peripheral edge area around the display area;

a frame disposed in front or in back of the display panel; and

a first elastic member and a second elastic member which are disposed at positions corresponding to the peripheral edge area of the frame, and each having a bonding surface on which an adhesive member is provided, wherein

a portion of the first elastic member and a portion of the second elastic member are disposed on the frame to overlap each other,

the bonding surface of the first elastic member has a first area overlapping the second elastic member and a second area overlapping the frame at a position near a center of the first elastic member relative to the first area, and

the adhesive member, provided on the bonding surface of the first elastic member, is divided between the first area and the second area.

2. The display device according to claim 1, wherein the adhesive member is divided at a plurality of portions between the first area and the second area.

3. The display device according to claim 1, wherein the first elastic member and the second elastic member are disposed to cross each other.

4. The display device according to claim 3, wherein

the bonding surface of the first elastic member has a third area bonded on the frame at a position opposite to the center of the first elastic member relative to the first area, and

the adhesive member provided on the bonding surface of the first elastic member is divided between the first area and the third area.

5. The display device according to claim 4, wherein the adhesive member provided on the bonding surface of the first elastic member is not disposed in the first area.

6. The display device according to claim 1, further comprising a third elastic member, which is disposed adjacent to the first elastic member, having a bonding surface on which the adhesive member is provided, wherein

a portion of the third elastic member is disposed on the frame to overlap a portion of the second elastic member,

the bonding surface of the third elastic member has a third area overlapping the second elastic member, and a fourth area overlapping the frame at a position near a center of the third elastic member relative to the third area, and

the adhesive member, provided on the bonding surface of the third elastic member, is divided between the third area and the fourth area.

7. The display device according to claim 1, further comprising a third elastic member disposed adjacent to the first elastic member, wherein

a portion of the second elastic member is disposed on the frame to overlap a portion of the third elastic member,

the bonding surface of the second elastic member has a third area overlapping a third elastic member, and a fourth area overlapping the frame at a position near a center of the second elastic member relative to the third area, and

the adhesive member, provided on the bonding surface of the second elastic member, is divided between the third area and the fourth area.

8. The display device according to claim 1, further comprising a first frame disposed in front of the display panel, and a second frame disposed in back of the display panel,

the first frame and the second frame each being configured to dispose the first elastic member and the second elastic member disposed to overlap the first elastic member.

9. The display device according to claim 1, wherein the bonding surface has a cut in a portion where the adhesive member is divided.

10. The display device according to claim 1, wherein the frame is formed into a rectangular frame shape corresponding to the peripheral edge area, and

the first elastic member and the second elastic member have a linear shape corresponding to sides of the frame.

11. The display device according to claim 1, wherein the frame is formed into a rectangular frame shape corresponding to the peripheral edge area, and

the first elastic member and the second elastic member have an L-shape corresponding to a long side and a short side of the frame.
