Problems solved by technology

However, with such a distribution method, the electric field E formed at the slit S between the first pixel electrode 122a and the second pixel electrode 122b will cause the liquid crystal molecules 132 at this position to fall into a state that cannot transmit light.
Thus, in image 3 Arrow A of A (three positions) produces three dark lines, which reduces the display quality of the multi-domain vertical alignment liquid crystal display panel 202
