The invention discloses a liquid crystal display screen. The liquid crystal display screen comprises an upper polaroid, an upper glass substrate, a liquid crystal layer, a metal wire grating polarizer, a composite optical layer and a lower glass substrate which are arranged in sequence from top to bottom, and further comprises a reflective sheet and a backlight source, wherein the backlight source is arranged on one side of the lower glass substrate; the reflective sheet coats the lower glass substrate and the backlight source; the top surface of the lower glass substrate is exposed out of the reflective sheet; the metal wire grating polarizer comprises a polarization substrate and a plurality of electrode strips which are formed on the polarization substrate through an etching process; the composite optical layer is used for adjusting light rays emitted from the upper surface of the lower glass substrate in order to form surface sources which are uniformly distributed. By adopting the liquid crystal display screen, a light guide plate of the liquid crystal display screen in the prior art is omitted, so that the overall thickness of the liquid crystal display screen is reduced greatly.
