The present invention provides a light guide plate and a backlight module, wherein the light guide plate comprises a bottom surface, a light incident surface and a light-emitting surface. The light-emitting surface and the bottom surface are positioned oppositely. The bottom surface comprises a plurality of screen dots. The screen dots comprise fluorescent powder and are selectively added with diffusion particles. The present invention prevents the phenomenon of color shift and the luminous efficiency degradation due to the fluorescent powder accelerated ageing because of closing to the LED chip.
