Problems solved by technology

In the prior art, reducing the thickness of the liquid crystal display usually adopts reducing the thickness of the glass substrate and reducing the thickness of the light guide plate and the optical film group in the backlight module. However, when the thickness of the glass substrate is too thin and is reduced to less than 2mm , the display effect of the liq

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of display devices, in particular to a liquid crystal display. Background technique [0002] A traditional liquid crystal display usually includes a liquid crystal display panel and a backlight module. The liquid crystal display screen includes an upper polarizer, an upper glass substrate, a liquid crystal layer, a lower glass substrate, a plurality of electrode strips arranged on the upper surface of the lower glass substrate, and a lower polarizer from top to bottom. The backlight module is divided into side-light backlight module and direct-light backlight module, but no matter what kind of backlight module is usually composed of optical film group, light guide plate, LED light bar, reflector, plastic frame and backplane superimposed assembly made. [0003] With the development of electronic products in the direction of thinner and lighter design, liquid crystal display screens are an important part of ...
