The light guide plate includes a rectangular light exit plane, a light entrance plane containing one side of the light exit plane, and a rear plane located on the side opposite from the light exit plane and scattering particles for scattering light propagating inside the light guide plate dispersed therein. The light guide plate has two layers, a first layer located on the side closer to the light exit plane and having a first particle density of the scattering particles, and a second layer located on the side opposite from the light exit plane and having a second particle density that is greater than the first particle density of the first layer. Npo and Npr satisfy Npo<Npr, where Npo is the first particle density and Npr is the second particle density. |
