The present invention discloses a light guide plate, a backlight module and a display apparatus, wherein a prism structure on a lighting outgoing surface of the light guide plate is designed through the steps of: for example using a mixing and matching structure formed by a plurality of different specifications of prisms; standardizing the specifications of the prism such as apex angle and corresponding transferring rate thereof; enabling the transferring rate of the prisms to change with the distance between the prism and a light incoming surface, thereby adjusting the light outgoing effect of the light guide plate, improving the backlight uniformity and further increasing the display quality of the display apparatus according to the combination of a plurality of design schemes.
