ABSTRACT:
A method for manufacturing a light guide plate mold includes the following steps: providing a substrate (20); coating a photo resist layer (21) on the substrate; exposing the photo resist layer to illuminating light (26) emitted by a light source (22); developing the photo resist layer; and etching the substrate to obtain the light guide plate mold. The illuminating light emitted from the light source has a predetermined distribution of intensity. The light guide plate mold is formed with high precision and accuracy.
