Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] Existing liquid crystal display panels include an array substrate, a color filter substrate, and a liquid crystal layer between the array substrate and the color filter substrate. The liquid crystal layer requires alignment films on the array substrate and the color filter substrate for alignment, and the liquid crystal material contains a small amount of ionic impurities, including a small amount of ionic impurities in the liquid crystal layer that may be introduced into the liquid crystal layer in the subsequent preparation process of the liquid crystal panel, such as color resist materials, sealant materials, or in the lamination process of the array substrate and the color filter substrate. pure. [0003] When the liquid crystal display panel is driven by AC, there is a situation where the posi...

Problems solved by technology

[0003] When the liquid crystal display panel is driven by AC, the positive and negative voltages deviate from the center of symmetry, and the voltage deviated from the center of symmetry is a DC bias voltage, which leads to the directional accumulation of mobile charges in the liquid crystal layer. pole, and further adsorb free ions to generate charges; as the voltage is applied for a longer time, the residual charge generated by the induced polarization inside the alignment film increases. When the voltage is not applied, the residual charge generated by the induced polarization forms a residual DC voltage. As a result, the liquid crystal molecules are not driven by the signal voltage, resulting in afterimages
