Abstract
A composite light guide plate manufacturing method includes the steps of providing a light guide substrate; providing a transfer membrane, which sequentially includes a substrate, a reflective layer and a diffusion microstructure; attaching the transfer membrane to the light guide substrate with a side of the transfer membrane, which has the diffusion microstructure thereon; and removing the substrate to expose the reflective layer.
