Grating, liquid crystal display device and manufacture methods of grating and liquid crystal display device

Abstract

The embodiment of the invention discloses a grating, a liquid crystal display device and manufacture methods of the grating and the liquid crystal display device, relating to the field of liquid crystal display and solving the problems of light waste caused in a manner that one part of light radiated by a backlight source is absorbed by a block matrix region and poorer utilization rate in the prior art. The grating provided by the embodiment of the invention comprises a plurality of three-primary-colour gratings arranged in parallel, each three-primary-color grating comprises a red R sub grating, a green G sub grating and a blue B sub grating which are arranged in parallel, each sub grating comprises an open region and a reflection region, the reflection region is arranged around the open region, and the sub grating corresponds to a pixel unit on an array substrate. The grating, the liquid crystal display device and manufacture methods of the grating and the liquid crystal display device, provided by the embodiment of the invention are applied to a system with liquid crystal display.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a grating sheet, a liquid crystal display device, a manufacturing method of the grating sheet, and a liquid crystal panel. Background technique [0002] Currently, if figure 1 As shown, the liquid crystal display device includes a backlight source 11 and a liquid crystal cell 12, and the liquid crystal cell 12 includes a lower polarizer 121, a thin film transistor array substrate 122, a liquid crystal layer 123, a color filter substrate 124, and an upper polarizer 125, wherein the thin film transistor array The substrate 122, the liquid crystal layer 123, and the color filter substrate 124 form a liquid crystal panel. The backlight 11 provides a white light source, and the transmission path of light irradiated by the backlight 11 is as follows: firstly, the polarized light is obtained through the lower polarizing plate 121, and then passes through the array substrate 122, t...
