A method for fabricating a mold for a light guide plate in accordance with the present invention generally includes the following steps: providing a substrate (18); and providing electron beams (15) to etch the substrate according to predetermined patterns. Because a focus diameter of the electron beams is adjustable, a very narrow line-width of the patterns can be obtained by employing the fine focus diameter of the electron beams. That is, the mold (18') fabricated by the present invention can have fine patterns at the nanoscale level. The light guide plate (22) formed using the mold has correspondingly fine patterns. These fine patterns can greatly enhance the quality and performance of the light guide plate.
