摘要： The present disclosure discloses a light guide plate, a backlight module and a liquid crystal module. The light guide plate includes a plurality of light guide blocks; the light guide blocks are doped with scattering particles. Since the light guide plate includes a plurality of light guide blocks, this can simplify the cutting of the light guide plate and the making of grid points. The light guide blocks are doped with scattering particles, so that most of rays incident upon the light guide blocks are scattered in a preset direction and guided to a middle part and the light-far end of the backlight module to compensate the brightness of the middle part and the light-far end, thus making the brightness of the side light type backlight display uniform.
