Abstract
A display panel and a display device are provided in an embodiment of the present disclosure. The display panel includes a first substrate and a second substrate that are disposed opposite each other. A liquid crystal layer is disposed between the first substrate and the second substrate and the liquid crystal layer is doped with a chiral agent. In the present disclosure, the liquid crystal layer of the display panel is doped with a chiral agent and a helical twisting force generated by the chiral agent is used to drive liquid crystal molecules around a pixel to rotate, which can reduce a dark region around the pixel and increase transmittance of the display panel.
