Profiled light guide plate, backlight module and liquid crystal displace device
Embodiments of the present invention relate to a profiled light guide plate, a backlight module and a liquid crystal display device. In the profiled light guided plate according to the embodiments of the present invention, because the reflectivity of the profiled assembly is less than that of the light entry assembly, the emergent angle of the light beam entering into the profiled assembly from the light entry assembly is larger than the incident angle thereof, which causes the light beam entering from the light entry assembly into the profiled assembly to converge towards the central part of the profiled assembly, away from the ramp of the profiled assembly, thereby decreasing the amount of light leakage from the ramp.
