Abstract
The time it takes for a liquid crystal display device picture to become homogeneous can be reduced to an acceptable extent by a suitable choice of the resistance and the capacitance of the orienting layers with respect to those of the liquid crystal layer. Possible DC voltages, which may occur in the case of a reset drive mode, can thus be rapidly eliminated.
