Abstract

The present invention provides a light guide plate and a method and a mold for manufacturing the same. The light guide plate comprises at least one incident surface, an exiting surface and a bottom surface, the exiting surface and bottom surface being disposed facing to each other and both being connected to the incident surface, the light guide plate having a cavity formed therein, wherein light incident from the incident surface exits the exiting surface after refracted and/or reflected by the cavity. With the light guide plate, light energy loss can be reduced and brightness of pictures can be improved.
