Abstract
A light guide plate, a backlight module and a display device are provided. The light guide plate includes a main body and an optical layer. The main body has a light-incident surface, a side surface and an optical surface. The light-incident surface and the side surface are respectively connected to the optical surface. The optical layer is correspondingly disposed on the side surface of the main body. In a reflectance characteristic of the optical layer, a total reflectance of the reflectance characteristic is composed of the diffuse reflectance and the parallel reflectance. The percentage value of the parallel reflectance to the total reflectance is less than 45 and larger than 25, including the end point.
