Therefore, in order to improve the viewing angle specification of the display, the pixel electrode in the display adopts a cross-domain design.
When a pixel electrode in a display adopts a transverse domain design, electric field force applied to liquid crystal molecules at the edge of the pixel and electric field force applied to liquid crystal molecules in the middle of the pixel are different, the arrangement direction of the liquid crystal molecules at the edge of the pixel along with the rise of voltage is different from the arrangement direction of the liquid crystal molecules in the middle of the pixel, black domain lines appear on a white picture, when sliding external force is applied to the surface of the display, the liquid crystal molecules are arranged in a disorder mode, the liquid crystal molecules at the edge of the pixel drive the liquid crystal molecules in the middle of the pixel, the liquid crystal molecules tend to be arranged in the same mode as the liquid crystal molecules at the edge of the pixel, the area of the black domain lines is increased, and therefore the brightness of the pixel is reduced, namely, the trace mura phenomenon is achieved.
