Claims18
A display device comprising:
- a receptacle comprising a sidewall section, and a support section extending from an inner side of the sidewall section;
- a liquid crystal panel and a backlight assembly, at least one of which is received in the receptacle;
- and
- an impact absorption member provided at an inner side surface of the sidewall section,
- wherein the entire receptacle comprises a metal,
- wherein the inner side surface of the sidewall section extends to the support section vertically,
- wherein at least one locking groove is formed at an inner side of at least one of the sidewall section and the support section,
- wherein a plurality of extensions are formed to extend further from one portion of the support section, the plurality of extension being coplanar with the support section, and the plurality of extensions are connected to the one portion of the support section along their entire lengths,
- wherein the backlight assembly comprises:
- an optical reflection member provided on a rear surface of the receptacle to cover a through hole formed by the support section;
- a light source provided at one side of the receptacle;
- a light guide plate to improve brightness uniformity of light generated from the light source;
- and
- an optical sheet provided on the light guide plate,
- wherein the light guide plate and the optical sheet comprise a protrusion coupled with the at least one locking groove,
- wherein the protrusion is formed in a fan shape, and
- wherein the impact absorption member is disposed on a lateral side of the liquid crystal panel and the optical sheet to contact both the liquid crystal panel and the optical sheet, the lateral side being a surface of the liquid crystal panel that is parallel to a thickness direction of the liquid crystal panel.
