Patent ID: 8308338

Claim:
A light guide plate, comprising: a transparent substrate having a first surface and a second surface opposite the first surface; and a plurality of first micro structures, disposed at least on the first surface of the transparent substrate, the first micro structures being separate from each other and each of the first micro structures comprising: a first coating layer formed on the first surface and comprising an adhesive material; and a second coating layer formed on at least a part of the first coating layer and comprising a light-diffusing material; and a plurality of second micro structures that are different to the first micro structures, the second micro structures disposed at least on the first surface of the transparent substrate, the second micro structures being separate from each other and each of the second micro structures comprising: a first coating layer formed on the first surface and comprising an adhesive material; and a second coating layer formed on at least a part of the first coating layer and comprising a light-diffusing material; wherein a distribution density of the first micro structures on the transparent substrate is different from a distribution density of the second micro structures on the transparent substrate; wherein the adhesive material of the first micro structures is different from the adhesive material of the second micro structures.
