Abstract

A display device is disclosed. In one embodiment, the display device includes a display panel displaying an image and a bottom chassis including a bottom portion where the display panel is mounted and a plurality of side walls connected with the bottom portion and facing a side surface of the display panel. At least two of the side walls include a base side wall and a reinforcing side wall integrally formed with the base side wall by a connection portion. The connection portion and the reinforcing side wall are bent from the base side wall and thus partially overlap the base side wall.

Claims

1. A display device comprising:

a display panel configured to display an image; and

a bottom chassis including a bottom portion where the display panel is mounted and a plurality of side walls connected with the bottom portion and facing a side surface of the display panel,

wherein at least two of the side walls respectively include base side walls and reinforcing side walls integrally formed with the base side walls by connection portions, and

wherein the connection portion and the reinforcing side wall are folded from the base side wall and partially overlap with the base side wall.

2. The display device of claim 1, wherein the height of the reinforcing side wall is smaller than that of the base side wall, and wherein the connection portion is formed at both ends of the reinforcing side wall.

3. The display device of claim 2, wherein the connection portion and the reinforcing side wall are folded to the inside of the base side wall such that the connection portion at least partially overlaps with both ends of the base side wall, and wherein the reinforcing side wall at least partially overlaps with a lower portion of the base side wall toward the bottom portion.

4. The display device of claim 2, further comprising a mold frame assembled with the bottom chassis at an inner side of the bottom chassis and formed in the shape of a substantially rectangular frame.

5. The display device of claim 4, wherein the mold frame is disposed in substantially parallel with the reinforcing side wall, and wherein the height of the mold frame is substantially equal to or greater than the height of the reinforcing side wall and less than the height of the base side wall.

6. The display device of claim 5, further comprising a backlight unit disposed in an inner space of the mold frame,

wherein the display panel is a liquid crystal display panel, and is disposed in substantially parallel with the base side wall on the mold frame and the backlight unit.

7. The display device of claim 5, further comprising a buffering member disposed in an inner space of the mold frame,

wherein the display panel is an organic light emitting diode display panel, and is disposed in substantially parallel with the base side wall on the mold frame and the buffering member.

8. The display device of claim 4, wherein the mold frame and the base side wall have substantially the same height, and contact the reinforcing side wall and are separated from the base side wall.

9. The display device of claim 4, wherein the mold frame and the base side wall have substantially the same height, and wherein the mold frame forms a protrusion portion toward the base side wall and contacts the reinforcing side wall and the base side wall.

10. The display device of claim 8, further comprising a backlight unit disposed in the inner space of the mold frame,

wherein the display panel is a liquid crystal display panel and is disposed on the backlight unit in the inner space of the mold frame.

11. The display device of claim 8, further comprising a buffering member disposed in the inner space of the mold frame,

wherein the display panel is an organic light emitting diode display panel, and is disposed on the buffering member in the inner space of the mold frame.

12. The display device of claim 1, wherein the display panel comprises a flexible circuit board fixed to one side end, and wherein the flexible circuit board is bent backward of the bottom chassis while surrounding a selected one of the side walls.

13. The display device of claim 12, wherein the connection portion and the reinforcing side wall are provided in at least two of the side walls, excluding the side wall surrounded by the flexible circuit board.
