Disclosed are a light guide plate and backlight module. The light guide plate comprises a bottom surface and a top surface opposite to the bottom surface. A plurality of micro-structure units are set up adjacently at the top surface or/and bottom surface of lateral side of the light guide plate. Each micro-structure unit comprises a plurality of branches of micro-structures, and a plurality of micro-structures in each micro-structure unit extend diffusely at the top surface or/and bottom surface of the light guide plate. It is capable of mixing light sufficiently in a shorter distance via the establishment of the light guide plate to attribute the light intensity of the side-light type backlight module even to avoid shadow without raising a frame thickness.
