摘要：
A light-transmitting substrate has an uneven profile on at least one surface thereof, the light-transmitting substrate contains a thermoplastic resin and a flat translucent particle; a tilt angle of the uneven profile on at least one surface of the light-transmitting substrate has the following distribution: (a) an integral value of frequencies of from 0° to less than 1.0° is from 0% to less than 25%, (b) an integral value of frequencies of from 1.0° to less than 10° is from 60% to less than 100%, and (c) an integral value of frequencies of 10° or more is from 0% to less than 25%, and an average distance between trough and crest in the uneven profile is from 10 to 300 μm.
