摘要：
A light guide includes a light guide substrate having a top surface through which light is to be emitted, a bottom surface, an incident edge surface through which incident light is to be introduced into the light guide substrate, and another edge surface. The another edge surface includes at least one micro structure operative to reflect at least a portion of the incident light, which travels through the light guide substrate and is incident on the another edge surface, back within the light guide substrate.
