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.

Abstract

Embodiments of the present invention provide a liquid crystal display panel and a liquid crystal display. The liquid crystal display panel includes a first substrate and a second substrate oppositely arranged, and a liquid crystal layer located between the first substrate and the second substrate. The display area of ​​the liquid crystal display panel is provided with a plurality of sub-pixel regions arranged in a matrix and a light-shielding region between two adjacent sub-pixel regions. The side of the first substrate adjacent to the liquid crystal layer is provided with a second An electrode layer, the first electrode layer corresponds to the sub-pixel area and the light-shielding area, and the side of the second substrate adjacent to the liquid crystal layer is provided with a second electrode layer and a third electrode layer that are independent of each other , the second electrode layer corresponds to the sub-pixel area, the third electrode layer corresponds to the light-shielding area, and a through hole is provided on the third electrode layer. The invention can improve the dark state light leakage problem of the 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] Such as 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 th...
