Abstract

A liquid crystal display of the present invention is adapted to perform initialization by inputting voltages with different polarities to two pixel electrodes (23á, 23â) adjacent in front and back direction. It is preferable that in the two pixel electrodes (23á, 23â) adjacent in front and back direction, the pixel electrode (23á) located on back side is provided with a first protrusion (232á) at a front side and back direction, the pixel electrode (231â) adjacent in front and back is provided with a second protrusion (23â) located on front side is provided with a second a second protrusion (234â) on a back side edge (233â)thereof.
