摘要： A pixel has a first liquid crystal domain. In the first liquid crystal domain, first and second pretilt directions of liquid crystal molecules, defined by first and second alignment films, respectively, intersect with each other at substantially right angles. Also, in the first liquid crystal domain, when a signal voltage is applied to the liquid crystal layer to display the highest gray scale, liquid crystal molecules, located around the center of a plane of the liquid crystal layer and around the middle of the thickness of the liquid crystal layer, are tilted in a first direction that substantially equally divides the first and second pretilt directions into two. A driver applies a signal voltage to the liquid crystal layer of the pixel every vertical scanning period. At least while display gray scales are changing from the lowest gray scale into the highest one, the driver applies a voltage that is at least 0.96 times as high as the threshold voltage Vth of the liquid crystal layer in a vertical scanning period just before the signal voltage is applied to display the highest gray scale.
