A light guide plate, a backlight module and a display. The light guide plate (10) comprises a light-output surface, a reflecting surface (104) opposite to the light-output surface, and at least one light-incident surface (102) connected to the light-output surface and the reflecting surface (104). The reflecting surface (104) is provided with a plurality of micro protrusion structures (101) that protrude towards the interior of the light guide plate (10). Each micro protrusion structure (101) comprises at least two side surfaces (1011) that are coated with high-reflectivity materials, and the at least two side surfaces (1011) coated with high-reflectivity materials form at least one angle facing the at least one light-incident surface (102). The distribution density of the micro protrusion structures (101) is decreased along with increase of the distance between the micro protrusion structures (101) and light sources. By means of the light guide plate, light can be reflected to positions corresponding to gaps of the light sources in a direction away from the light sources, absorption loss of the light at the portions of the light guide plate away from the light sources can be reduced, and the uniformity of the emitted light can be improved. |
