  • Publication number: 20160116785
    Abstract: A liquid crystal display includes first and second sub-pixels charged with the same voltage during a first period. The voltage charged in the second sub-pixel is decreased after the first period. Since the voltage level of the first sub-pixel is different from the voltage level of the second sub-pixel after the first period, liquid crystal molecules disposed corresponding to the first sub-pixel are aligned in a direction different from that of liquid crystal molecules disposed corresponding to the second sub-pixel. Thus, a side viewing angle of the liquid crystal display is improved.
