Abstract
A light guide plate () for transmitting light beams from a light source to an LCD (liquid crystal display) includes: an incident surface () for introducing light beams into the light guide plate; an emitting surface () for uniformly transmitting light beams out from the light guide plate; and a bottom surface () opposite to the emitting surface for reflecting the light beams in directions toward the emitting surface. The light guide plate further provides a plurality of concavities () on the emitting surface, for converging the light beams into the LCD. The light guide plate is a relatively simple, single integrated structure, and can obviate the need for a brightness layer in an associated LCD device.
