Problems solved by technology

In this method, the light-transmitting area of ​​the sub-pixel with the largest light-transmitting area is limited by the pixel size and process capability, and cannot be adjusted. Only by reducing the light-transmitting area of ​​other sub-pixels can different light-transmitting area ratios of RGB pixels be realized. , which reduces the brightness of the display

Abstract

The invention provides a liquid crystal display device, and belongs to the field of liquid crystal display. The liquid crystal display device comprises a backlight and a liquid crystal display panel, wherein a plurality of pixel units are formed on the liquid crystal display panel; each of the pixel units comprises at least a sub-pixel; each of the sub-pixels is divided into a reflecting zone and a transmitting zone; reflecting patterns positioned between the liquid crystal display panel and the backlight are formed in the reflecting zone. The liquid crystal display device adopting technical scheme can adjust the reflecting patterns under the conditions that the liquid crystal display panel and the backlight are invariable to adjust different transmitting area ratios of the sub-pixels, so as to meet the requirement on different white light color coordinates, and further ensure the brightness of the liquid crystal display panel.

Description

Technical field [0001] The invention relates to the field of liquid crystal display, in particular to a liquid crystal display device. Background technique [0002] Such as figure 1 As shown, the traditional liquid crystal display panel includes: an upper polarizer 1, a color film substrate 2, a black matrix 3 and R / G / B (Red Green Blue) resin 4, and an array substrate provided on the color film substrate 2. 7. The lower polarizer 8, the liquid crystal layer 6 arranged between the array substrate 7 and the color filter substrate 2, the alignment layer 5 on both sides of the liquid crystal layer 6, and also includes a pixel matrix arranged on the array substrate. Each pixel is generally It is further divided into three sub-pixels of RGB (Red Green Blue, red, green and blue). Correspondingly, corresponding sub-pixel areas are also provided on the color film substrate, and each sub-pixel area is provided with a resin layer corresponding to the corresponding color. The white light co...
