摘要： A matrix liquid crystal display is capable of displaying a still displayed picture by using a hysteresis characteristic of an antiferrodielectric liquid crystal medium or the like. The picture is displayed by applying scan signals from a row driving circuit and data signals from a column driving circuit to a matrix liquid crystal display having an antiferrodielectric liquid crystal medium or the like. When a voltage for stilling the display of the picture is provided to a still signal input terminal, a timing circuit interrupts the application of a clock signal output from a control circuit to the row driving circuit in response to a generated vertical synchronizing signal. When the clock signal is stopped, a holding voltage is applied to each pixel of the liquid crystal display and the displayed picture is put into a still state by the hysteresis characteristic of the antiferrodielectric liquid crystal medium or the like.
