Abstract
A light guide plate includes a light guide layer and a metal reflective layer. The light guide layer has a light emitting surface, a bottom surface and a light incident surface. The light incident surface is located between the light emitting surface and the bottom surface. The metal reflective layer is coated on the bottom surface of the light guide layer. Additionally, an average reflectance of the metal reflective layer for light in a wavelength range of 400 to 550 nanometers is greater than an average reflectance of the metal reflective layer for light in a wavelength range of 550 to 700 nanometers.
