Liquid crystal display panel and liquid crystal display

Abstract

The embodiment of the invention provides a liquid crystal display panel and a liquid crystal display. The liquid crystal display panel comprises a first substrate, a second substrate and a liquid crystal layer, wherein the first substrate and the second substrate are oppositely arranged, and the liquid crystal layer is arranged between the first substrate and the second substrate; a plurality of subpixel areas which are distributed in a matrix shape and light shading areas arranged between every two adjacent subpixel areas are arranged in a display area of the liquid crystal display panel, a first electrode layer is arranged on one side, adjacent to the liquid crystal layer, of the first substrate, the first electrode layer corresponds to the subpixel areas and the light shading areas, a second electrode layer and a third electrode layer which are independently arranged are arranged on one side, adjacent to the liquid crystal layer, of the second substrate, the second electrode layer corresponds to the subpixel areas, the third electrode layer corresponds to the light shading areas, and a through hole is formed in the third electrode layer. The liquid crystal display panel disclosed by the invention can obviously solve the problems of a dark state and light leakage of a liquid crystal display panel.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display panel and a liquid crystal display. Background technique [0002] In a liquid crystal display (LCD for short), since the liquid crystal display panel itself does not emit light, a backlight source provided by a backlight module must be used to enable the liquid crystal display to display images. [0003] like figure 1 As shown, the liquid crystal display in the prior art includes a liquid crystal display panel 101, an upper polarizer 1021 and a lower polarizer 1022 respectively located on the upper and lower surfaces of the liquid crystal display panel 101, and an upper polarizer 1022 located away from the liquid crystal display. A backlight 103 on one side of the panel 101 ; wherein the liquid crystal display panel 101 includes an array substrate 1011 , a color filter substrate 1012 , and a liquid crystal layer 1013 disposed between the a...

Problems solved by technology

Due to the birefringence characteristics of liquid crystal molecules, this part of the linearly polarized light obliquely incident on the liquid crystal layer 1013 will undergo a birefringence effect to form elliptically polarized light, which cannot be completely absorbed when it enters the upper polarizer 1021, resulting in It prevents the light leakage phenomenon of the liquid crystal display when it is displayed in the dark state, and further limits the improvement of its contrast ratio.
