Abstract
The wedge-shaped light guide plate has a number of reflection structures with gaps therebetween arranged along the light reflection plane. Each reflection structure from a previous gap contains sequentially a slant surface extended away from the light emission surface, a second reflection surface further slanting away from the light emission plane, and a first reflection surface slanting towards the light emission plane to connect to a next gap. The second and first reflection surfaces form a prism element. In one embodiment of the present invention, the reflection structures are more densely arranged as they are more distant from the light source. In an alternative embodiment of the present invention, the reflection structures are arranged uniformly.
