Abstract

A multi-domain liquid crystal display device having sharp contrast and excellent viewing angle characteristics is provided without increased complicated processes such as microfabrication for a common electrode or without the necessity for highly sophisticated laminating technology. The multi-domain liquid crystal display device is composed of a control electrode connected to a source terminal being one of terminals of a TFT (Thin Film Transistor) serving as a switching device, a picture electrode having an aperture section provided with one coupling capacitor connected between the pixel electrode and the control electrode, wherein a partial voltage of a signal voltage is applied to the pixel electrode through the other coupling capacitor.
