Abstract
After supply of power, a liquid crystal display device performing transition from a first state to a second state different from the first state before a display operation is provided with a transition nucleus forming portion around a pixel electrode or inside. The transition nucleus forming portion performs transition to the second state prior to other portion during a transition drive period. The transition nucleus forming portion of the pixel electrode has an edge portion formed into a reverse taper shape decreasing in its thickness toward the tip end. Therefore, transition from a splay alignment to a bend alignment is performed with simple element and drive circuit configuration in all pixels.
