The present disclosure provides a fabrication method of a light guide plate including the following steps. A first substrate with a processing plane is provided. A plurality of first mold trenches are formed along a second direction on the processing plane by a first cutter, where the first mold trenches are connected to each other. A plurality of second mold trenches are formed along a first direction different from the second direction in a first processing region of the processing plane by a second cutter, where the first processing region is near to a first edge of the processing plane. A light-emitting surface of the light guide plate is formed by using the first substrate as a mold.
