Abstract: A light guide plate includes a flat plate body and multiple protrusion platforms. The flat plate body includes a top surface and a bottom surface. The multiple protrusion platforms are disposed on the bottom surface. A protrusion surface of each protrusion platform is formed by multiple pyramids. A backlight module and a liquid crystal display are also disclosed. After lights emitting from the light source and entering the light guide plate irradiates the protrusion platform, a total reflection of the lights will be broken. Accordingly, a portion of lights emit out from the top surface, the other portion of the lights emit out from the bottom surface and be reflected back to the light guide plate. The protrusion platforms can replace the mesh dot and the reflective sheet to reduce a thickness of the backlight module to increase a light utilization rate, reduce the manufacturing process and production cost.
