Zusammenfassung:PROBLEM TO BE SOLVED: To provide a light guide plate that efficiently effectively emits light having entered the plate.SOLUTION: A light guide plate has a light-emitting surface and a back surface on an opposite side to the light-emitting surface. The light guide plate includes: a light entering surface, an opposite surface on an opposite side to the light entering surface, and a side surface formed so as to bridge between the light entering surface and the opposite surface, which are formed between the light-emitting surface and the back surface. The side surface is a smooth surface having surface roughness Rz of 380 nm or less.
