摘要:
An electronic apparatus includes a liquid crystal display device. The liquid crystal display device comprises first and second light sources, a light guide plate, and a liquid crystal unit. The first light source is disposed on one of two opposing side surfaces of the light guide plate. The second light source is disposed on the other of the two opposing side surfaces of the light guide plate. A first plurality of substantially parallel grooves are formed in a first surface of the light guide plate which is substantially parallel with a display surface of the liquid crystal unit. A second plurality of substantially parallel grooves are formed in a second surface opposing the first surface of the light guide plate. At least one of a dimension and density of the first plurality of grooves substantially monotonically changes from one in the vicinity of one of the light sources to one in the vicinity of the other of the light sources.
