A television receiver is equipped with a liquid crystal matrix display panel having the drive electrodes arranged such as to form a plurality of regions, with the regions each successively entering a drive phase of operation in which selection and bias drive signals are applied to the display element electrodes and a rest phase of operation in which a voltage level substantially equal to zero is applied between the display element electrodes, with only one region operating in the drive phase at a time and the remaining regions operating in the rest phase. The display contrast attainable with a given number of rows of picture elements in the display can thereby be substantially increased, e.g. can be effectively doubled for the case of a display divided into two regions, without the need to utilize large-capacity video memory circuits.
