Abstract

An active matrix liquid crystal display is disclosed in which a better image quality is obtained by specifying a relation between voltages applied to the liquid crystal display. Also, a better holding characteristic is obtained by selecting the channel resistance R.sub.OFF of a thin film transistor in its OFF state to be not smaller than 10.sup.12 .OMEGA..
