Abstract:
A light guide plate, a backlight module, and a display device. The light guide plate comprises a main body, a plurality of first strip-shaped microstructures, a plurality of second strip-shaped microstructures, and a plurality of third strip-shaped microstructures. The main body is provided with a light incident surface, and an optical surface connected to the light incident surface. The optical surface is provided with a first region and a second region, the first region being closer to the light incident surface than the second region. The first strip-shaped microstructures are disposed in the first region, and each of the first strip-shaped microstructures extends in a direction perpendicular to the light incident surface. The second strip-shaped microstructures are disposed in the second region, and each of the second strip-shaped microstructures extends in said direction. The width of an end of each second strip-shaped microstructure that is close to the light incident surface is smaller than the width of another end that is far from the light incident surface. The third strip-shaped microstructures are disposed on part or all areas of the optical surface in which the first strip-shaped microstructures and the second strip-shaped microstructures are not disposed.
