Abstract

PURPOSE: To obtain an excellent contrast unit with liquid crystal long in life, by applying a voltage, which has positive and negative pulse-zero voltage periods, to a source line and by separately applying a common voltage corresponding to scanning lines of a gate line.
CONSTITUTION: At intersections between several source lines 1 and several gate lines 2, thin-film transistors TFT3 are formed and liquid-crystal bodies 4 are held between striped common electrode 31 and TFTs 3, thereby obtaining a unit using bodies 4 as picture elements. In this unit, when picture element (ij) at the intersection between source line (i) and gate line (j) generates voltage VLCij by source voltage VSi and gate voltage VGj in case of an odd frame and write operation is performed and in case of an even frame, no write operation is done since VSi is zero, but voltage VCj equal in waveform and level to VLCij is applied reversely from common electrode 31. To cover positive and negative asymmetrical characteristics of the TFT, positive and negative pulse widths of voltage SSi are varied and when the TFT is OFF, positive and negative discharge voltages are made zero; and then, AC driving operation containing no DC component is made possible only in one direction with characteristics excellent.
