Patent ID: 8009246

Claim:
A liquid crystal display device, comprising: a liquid crystal panel; a plurality of linear light sources disposed on a rear surface side of the liquid crystal panel to irradiate light beams to the liquid crystal panel; and a rectangular frame disposed on a rear surface side of the linear light sources, wherein reflecting portions for reflecting light beams from the linear light sources to be irradiated to the liquid crystal panel are provided on inner wall surfaces of the frame, wherein the linear light sources are provided on a side surface of the frame so as to extend in a horizontal direction of the liquid crystal panel, wherein valleys are provided in portions of the reflecting portions provided on the side surfaces of the frame so as to surround the portions where the linear light sources are provided, and wherein the valleys form curved reflecting portions at the circumferences of the portions where the linear light sources are provided, wherein the light beams from the linear light sources are focused onto the circumferences of electrode portions of the linear light sources by the curved reflecting portions.
