Description
Technical Field
The invention relates to the technical field of display panels, in particular to a liquid crystal display panel and a display device.
Background
The liquid crystal display panel displays an image by using optical anisotropy and birefringence characteristics of liquid crystal molecules. In the liquid crystal display panel, the surfaces of the array substrate and the color film substrate are arranged opposite to each other, electrodes for generating an electric field are formed on the surfaces of the oppositely arranged substrates, liquid crystal materials are injected between the substrates, and then the electric field is generated by applying voltage to the electrodes on the surfaces of the substrates to change the arrangement direction of liquid crystal molecules.
In order to enable liquid crystal to be injected between the array substrate and the color filter substrate of the display panel, a spacer needs to be provided therebetween to provide a desired spacing. However, on the one hand, under high temperature conditions, the liquid crystal in the liquid crystal display panel is thermally expanded significantly more than other components, resulting in an increase in the cell thickness of the liquid crystal cell assembly, and the spacer is not thermally expanded to a corresponding degree, easily resulting in the liquid crystal in the vertically placed liquid crystal display panel flowing down as a whole due to the action of gravity. This is a so-called gravity display unevenness (gravitymura) defect at high temperature. On the other hand, when the liquid crystal display panel is in a low temperature state, the liquid crystal is thermally shrunk more than other components, i.e., the liquid crystal cannot fill the entire liquid crystal cell assembly and vacuum bubbles appear, while still maintaining the cell thickness of the liquid crystal cell. This is a so-called bubble (bubble) defect at low temperature. The defects limit the application conditions of the liquid crystal display device, influence the display effect of the liquid crystal display device and further reduce the user experience. In the manufacturing process, the allowable liquid crystal amount control range in the case where gravity display unevenness defect at high temperature and bubble defect at low temperature do not occur is called lcmargin (liquidcrystal margin).
