Abstract
A light guide plate includes a transparent substrate and a plurality of micro structures. The transparent substrate has a first surface and a second surface opposite the first surface, and the micro structures are disposed at least on the first surface of the transparent substrate and are separate from each other. Each of the micro structures includes a first coating layer and a second coating layer. The first coating layer is formed on the first surface and includes an adhesive material. The second coating layer is formed on at least a part of the first coating layer and includes a light-diffusing material.
