The capacitance is related to the film thickness of the second domain protection layer 223, and the capacitance is adjusted by the different film thicknesses, so that different domain regions corresponding to different display viewing angles are achieved, and therefore, the heights of the first domain protection layer 213 and the second domain protection layer 223 are set to be different, and the height direction is the extending direction from the first domain substrate 211 to the first domain protection layer 213.
In some embodiments of the present application, if the pixel structure is a two-domain pixel structure, in order to adjust the display viewing angles of different regions, the film layers of the protective layer of the two-domain regions may be set to different heights as described in the above embodiments.
