Abstract
A backlight module includes at least one point light source and a light guide plate. The light guide plate includes a light emitting surface, a bottom surface, a light incident surface, a first side surface, a second side surface, a first microstructure, and a second microstructure. The bottom surface is opposite to the light emitting surface, the light incident surface connects the light emitting surface and the bottom surface, the point light source is disposed adjacent to the light incident surface, and the first microstructure is formed on the light incident surface. The first side surface is opposite to the light incident surface and connects the light emitting surface and the bottom surface, and the second side surface connects the light emitting surface, the bottom surface, the light incident surface, and the first side surface. The second microstructure is formed on the second side surface.
