Abstract: A light guide plate includes a light incident surface, a light emitting surface, a bottom surface, a first lateral surface, and a second lateral surface. The light incident surface has a plurality of elongated optical microstructures, and each elongated optical microstructure has an inclined surface and a curved surface connected with each other. The light guide plate is capable of increasing uniformity and utilization rate of light beam emitting from the light guide plate. A backlight module using the light guide plate is also provided.
