Problems solved by technology

[0005] Unfortunately, in the pixel structure 100B, although the formation of the slit 122 in the pixel electrode 120 is helpful to increase the reaction rate of the liquid crystal molecules, when the distance d is too large, the design of the slit 122 is prone to discontinuity of the liquid crystal molecules. , resulting in the uncertainty of the tilting direction of the liquid crystal molecules
In addition, although the design of the pixel structure 100C can increase the reaction rate of the liquid crystal molecules and help align the liquid crystal molecules in the correct direction of inversion, the design of the slit 124 will sacrifice more display area openings than the design of the slit 122 Rate
In short, none of these methods can improve the display effect of the multi-domain vertical alignment liquid crystal display panel while maintaining a good aperture ratio of the display area.
