Problems solved by technology

However, in this way, under the current pixel design framework, there must be a certain area around the pixel that is not ideal, that is, the dark grain area
[0004] That is to say, in the prior art, there is a large area of ​​dark stripes around the pixels of the display panel, which reduces the transmittance of the display panel.

Abstract

The embodiment of the present application discloses a display panel and a display device. The display panel includes a first substrate and a second substrate oppositely arranged, a liquid crystal layer is arranged between the first substrate and the second substrate, and the liquid crystal layer is doped with hand sex agent. In the present application, a chiral agent is doped in the liquid crystal layer of the display panel, and the helical twisting force generated by the chiral agent is used to drive the liquid crystal molecules around the pixel to rotate, which can reduce the dark area around the pixel and improve the transmittance of the display panel.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] PSVA (Polmer Stabilized Vertically Aligned), the Chinese translation of polymer stabilized vertically aligned liquid crystal, is a new type of liquid crystal display technology. PSVA technology has the following advantages: ①High contrast, the static contrast ratio can reach 16000:1; ②Wide viewing angle, large viewing angle with low color shift less than 0.02, which meets the needs of multiple people watching TV; ③Fast response, dynamic image response speed is less than 5ms ; ④Low power consumption: higher penetration rate (greater than 30%), can provide more energy-saving backlight modules; ⑤Applicable to the development of factories of all generations, and has been verified in the 8.5-generation line. [0003] PSVA display mode needs to add ultraviolet light irradiation process in the panel manufact...
