Abstract

A display device includes a light source unit, a light guide plate including a light incident surface, an opposite surface, a light exit surface, and a light exit rear surface, a display panel provided on the light exit surface, a bottom chassis for housing the light guide plate, and an anti-static electricity member including a fluoride resin and contacting the bottom chassis, where the bottom chassis includes a bottom section and a sidewall section perpendicularly connected from the bottom section, and the sidewall section includes a first sidewall section more adjacent close to the light incident surface than the opposite surface, a second sidewall section, a third sidewall section, and the fourth sidewall section, and the anti-static electricity member is provided between the first sidewall section and the light source unit and contacting at least a portion of the first sidewall section.

First claim

What is claimed is:

1 . A display device comprising:
a light source unit; a light guide plate including a light incident surface which receives light from the light source unit, an opposite surface facing the light incident surface, a light exit surface which connects the light incident surface and the opposite surface to each other, and a light exit rear surface facing the light exit surface; a display panel provided on the light exit surface; a bottom chassis which houses the light guide plate therein; and an anti-static electricity member including a fluoride resin and contacting the bottom chassis, wherein the bottom chassis comprises a bottom section and a sidewall section, wherein the sidewall section comprises: a first sidewall section more adjacent to the light incident surface than the opposite surface; a second sidewall section facing the first sidewall section; a third sidewall section which connects the first and second sidewall sections to each other; and a fourth sidewall section facing the third sidewall section, and wherein the anti-static electricity member is provided between the first sidewall section and the light source unit, and contacts at least a portion of the first sidewall section.

2 . The display device of claim 1 , wherein the fluoride resin comprises one of polytetrafluoroethylene (“PTFE”), perfluoroalkoxy (“PFA”), fluorinated ethylene propylene (“FEP”), ethylene tetrafluoroethylene (“ETFE”), ethylene-chlorotrifluoroethylene (“ECTFE”), and any combination thereof.

3 . The display device of claim 1 , wherein the first sidewall section comprises a first inner side surface on which the anti-static electricity member is provided and which is not exposed to an outside by the anti-static electricity member.

4 . The display device of claim 1 , wherein the anti-static electricity member comprises:
a first sub-anti-static electricity member contacting the at least the portion of the first sidewall section; and a second sub-anti-static electricity member contacting at least a portion of the bottom section.

5 . The display device of claim 4 , wherein the first and second sub-anti-static electricity members are unitary.

6 . The display device of claim 5 , wherein the light source unit comprises:
a printed circuit board; and a light source provided on the printed circuit board, wherein the printed circuit board is provided on the bottom section, and wherein the second sub-anti-static electricity member is provided between the bottom section and the printed circuit board, and contacts each of the bottom section and the printed circuit board.

7 . The display device of claim 1 , wherein the bottom chassis further comprises a cover section which perpendicularly extends from the first sidewall section and is opposed to the bottom section.

8 . The display device of claim 7 , wherein the cover section overlaps a portion of the bottom section when viewed in a plane.

9 . The display device of claim 7 , wherein the anti-static electricity member comprises:
a first sub-anti-static electricity member contacting the at least the portion of the first sidewall section; a second sub-anti-static electricity member contacting at least a portion of the bottom section; and a third sub-anti-static electricity member contacting at least a portion of the cover section.

10 . The display device of claim 9 , wherein the first, second, and third sub-anti-static electricity members are unitary.

11 . The display device of claim 1 , wherein the anti-static electricity member comprises:
an adhesive layer contacting the at least a portion of the first sidewall section; a metal layer spaced apart from the first sidewall section and contacting the adhesive layer; and a fluoride resin layer including the fluoride resin and contacting the metal layer.

12 . The display device of claim 11 , wherein the light source unit comprises a printed circuit board and a light source provided on the printed circuit board, and
wherein the printed circuit board contacts the bottom section.

13 . The display device of claim 12 , wherein one end of the printed circuit board contacts a portion of the fluoride resin layer.

14 . The display device of claim 1 , wherein the anti-static electricity member is spaced apart from the second sidewall section.

15 . The display device of claim 1 , wherein the anti-static electricity member has a thickness in a range from about 50 micrometers to about 70 micrometers.

16 . The display device of claim 1 , wherein the bottom chassis comprises a conductive material.
