Once the liquid crystal molecules have an unintended tilt direction, the transmittance of the liquid crystal display panel is reduced, the display effect is affected, and a stable wide-angle function cannot be realized.
In order to solve the above problems, different driving efficiencies can be generated for the liquid crystal layer under the same driving voltage by setting different color resistance (filter layer) thicknesses of the main pixel region and the sub-pixel region, thereby improving the wide-viewing angle display effect of the assembled display device.
However, since different color resist thicknesses are directly prepared, the brightness and the color of areas with different thicknesses are different, and the phenomenon of obvious visual color nonuniformity in the surface is easily caused, so that the granular color is presented.
