ABSTRACT:
A method for fabricating a light guide plate (LGP) includes: providing a substrate (300) having a thermal stripping layer (400) and a metal layer (500) sequentially coated thereon; coating a photo-resist layer (600) on the metal layer; exposing and developing the photo-resist layer to form a photo-resist pattern (620); etching the substrate to form a metal pattern (540); removing the photo-resist pattern; disposing the substrate having the metal pattern between a case mold (720) and a cover mold (740), wherein the metal pattern faces the cover mold; sealing the cover mold and the case mold around the substrate having the metal pattern, wherein a cavity (760) is defined between the cover mold and the substrate having the metal pattern, and molding an LGP (800) in the cavity; and separating the thermal stripping layer and substrate from the LGP, such that the metal pattern remains embedded in the LGP.
