Abstract: A light guide plate comprises a light incidence surface for receiving light rays; a transforming fluorescent powder disposed on the light incidence surface for converting the light rays into white rays; a reflection surface for reflecting the light rays and destroying total internal reflection formed inside the light guide plate to generate planar light rays; a light emitting surface for emitting the planar light rays; and a lateral reflection surface disposed away from the light incidence surface for reflecting the light rays from the light incidence surface and the reflection surface; the lateral reflection surface having a compensative fluorescent powder disposed thereon for adjusting a color of the planar light rays. The light guide plate can reduce the backlight color difference for a panel of a single-end incident type to improve visual quality level and the quality of products.
