Abstract

An active matrix liquid crystal display device has a semiconductor substrate on which a plurality of pixel (including a plurality of pixel transistors and a plurality of pixel electrodes) arranged at positions determined by a plurality of data bus lines and a plurality of scanning bus lines, a counter substrate provided opposite the pixel electrodes, and a liquid crystal material provided between the semiconductor substrate and the counter substrate. Semiconductor regions having a conductivity opposite that of the semiconductor substrate are formed under the pixel transistors with an insulating film provided therebetween, such that a potential of the semiconductor regions, varies, e.g., is time dependant.
