Disclosed is an active matrix liquid crystal display device designed
mainly for alternating electric current drive, in which orientation
processing (monostabilization) is performed by a direct current power
supply or a direct current voltage applied to a ferroelectric liquid
crystal. The liquid crystal is made to respond, and is made monostable
while a voltage level is maintained by a storage capacitor. In addition,
the liquid crystal may also be made monostable while maintaining a gate
clock pulse at a constant level. After forming a transparent conductive
film on an element substrate, elements such as TFTs are formed. An
electric field is applied by a direct current voltage source between an
electrode formed on an opposing substrate and the transparent conductive
film. An electric field is applied by a direct current voltage source
between the electrode formed on the opposing substrate and the
transparent conductive film formed on the back side of the element
substrate.
