Abstract
A light guide plate includes an incidence surface and an output surface. The incidence surface is an end surface on which light emitted from a light source is incident. The output surface is a surface from which incident light coming from the incidence surface is outputted, and is a plane orthogonal to a thickness direction. The incidence surface is at least partially curved toward the light source, when viewed in a cross-section cut along a plane parallel to both a thickness direction of the light guide plate and an arrangement direction in which the light source and the light guide plate are arranged.
