Light Guide Plate and Backlight Module

摘要

A light guide plate includes a plate body and a light incident portion, wherein the plate body has a top plate surface. The light incident portion is formed on a side of the plate body and has a thickness increasing as the light incident portion extends away from a center of the plate body. In addition, the light incident portion has a top surface connected to the top plate surface and lifted from the top plate surface to include an angle with the top plate surface. The top surface includes a first incline and a second incline, wherein the first incline connects to a side of the top plate surface and has a first average slope. The second incline has a side connected to a side of the first incline opposite to the top plate surface and has a second average slope larger than the first average slope.
