Abstract:
A method for producing a light guide plate involves a peeling step, a water-rinsing step, and a printing step. In the peeling step, a masking film (MF) bonded to the surface of a light-transmissive resin plate (35) is peeled off therefrom. In the water-rinsing step, the surface (32) of the light-transmissive resin plate (35) from which the masking film (MF) was peeled is rinsed with water. In the printing step, an ink is arranged on the water-rinsed surface (32) of the light-transmissive resin plate (35) to thereby print a pattern (37) consisting of dots.
