ABSTRACT:
In a liquid crystal display device in which in order to prevent image sticking in a half tone type MVA using a floating sub-pixel, a second TFT is provided between a sub-pixel directly connected to a TFT and the floating sub-pixel, its alignment is improved and a display quality is improved. A control capacitance electrode of an adjacent pixel is extended to provide an alignment control electrode in a corner portion of a pixel in which a propagation distance of liquid crystal alignment is long, and the propagation distance of the liquid crystal alignment is shortened, and at the same time, a slit part is formed of electrodes different from each other in voltage polarity to stabilize the alignment.
