<p><P>PROBLEM TO BE SOLVED: To reduce the size and the costs of a liquid crystal display device using a liquid crystal panel with a memory effect, and to improve the display quality. <P>SOLUTION: A scanning electrode driving circuit 32 and a signal electrode driving circuit 31 of a driving circuit 30 applies, to scanning electrodes of a liquid crystal panel 40 with memory effect, a scanning voltage TPV in a voltage waveform composed of 0 V and three values which are positive or negative unipolar (VH, VD and VS), and also applies, to signal electrodes, a signal voltage SGV in a voltage waveform composed of 0 V and three values having a same polarity as the scanning voltage. Further, image data is displayed at a pixel of the liquid crystal panel 40 with memory effect during three scanning periods such as a correction period for correcting the alternation, a reset period for resetting the image, and a selection period for writing new image, and in the three scanning periods, the voltage to be applied between the scanning electrode and the signal electrode is made completely alternating. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
