Apparatus and method for manufacturing light guide plate

The present invention relates to an apparatus and a method for manufacturing a light guide plate, to an apparatus and method for forming an optical pattern in a light guide plate to provide more specifically, a uniform luminance. According to the present invention, the pressing portion 12 having the two pressure rollers 11 and 12 opposed; The two of the stamper 13 fixed to the outer periphery of at least one pressing roller of the pressing rollers (11, 12); And the two light guide plate production apparatus and a production method using the same light guide plate comprising a pressing force control unit for controlling the pressing force acting on the light guide plate substrate is provided in the course of the light guide plate substrate passes between the pressure roller (11, 12).
