LIGHT GUIDE PLATE, BACKLIGHT MODULE, AND DISPLAY DEVI

摘要

A light guide plate includes a light exit surface, a reflection surface opposite to the light exit surface, and at least one light incidence surface connecting to the light exit surface and the reflection surface. The reflection surface includes a plurality of minute projection structures projecting toward interior of the light guide plate. Each of the minute projection structures includes at least two side faces coated with a high reflectivity material. The at least two high reflectivity material coated side faces form at least one included angle pointing toward the at least one light incidence surface. The minute projection structures have a distribution density that is decreased with an increase of a distance thereof from the light sources.
