Abstract
A method for fabricating a light guide plate includes the following steps. Injection molding a light guide plate to obtain a light guide plate with a stub. Cutting away the stub to obtain a light guide plate with a cut edge. Providing a thermal resetting apparatus having an nano release material layer. A thermal melting temperature of the nano release material layer is higher than that of the light guide plate, heating the thermal resetting apparatus to make a temperature of the nano release material layer higher than the thermal melting temperature of the nano release material layer. And resetting the cut edge of the light guide plate by contacting the nano release material layer of the thermal resetting apparatus with the cut edge of the light guide plate to obtain a light guide plate with a smooth edge.
