A liquid crystal display (3) in accordance with one embodiment of the present invention includes a liquid crystal panel and a backlight module (36). The liquid crystal panel has a reflective polarizing element (342). The backlight module has a light source (361), a light guide plate (362), a reflector (365), and a quarter-wave plate (366). The light source is disposed adjacent to the light guide plate, and the reflector, the light guide plate and the quarter-wave plate are stacked together in order. The liquid crystal panel is located on the backlight module, and the reflective polarizing element of the liquid crystal panel faces toward the quarter-wave plate of the backlight module. The liquid crystal display3has a high brightness since light energy is efficiently used.
