Zusammenfassung:	PROBLEM TO BE SOLVED: To make a high speed switching possible while keeping the delay time from a blanking pulse to a strobe pulse short. SOLUTION: In the matrix type liquid crystal display device provided with matrix like pixels, the pixels are addressed by a data pulse given to row electrode lines 5... and the strobe pulse given to column electrode lines 6... The strobe pulse switches the pixel selected by the data pulse from a dark state to bright state under the effect of difference voltage between both pulses. Further, the blanking pulse for setting the pixel in the dark state before the strobe pulse is given to the row electrode lines 5... Each blanking pulse contains a blanking part of one polarity for switching the pixel to an area sufficiently switched to the dark state, and a succeeding part of an opposite polarity aiding the mitigation of the pixel to the area where the dark state is mitigated making a high speed switching from the area sufficiently switched to the dark state to the bright state possible.
