Liquid crystal display device with matrix electrode structure with reduced flicker

摘要

The present invention provides a liquid crystal display device having a matrix electrode structure in which flicker of picture images displayed on a panel(10) is invisible. Scanning electrodes(Y1 through Yn) of the matrix are driven by alternating voltages which include voltages for holding picture images displayed on the panel. Refresh pulse voltages higher than the holding voltages are imposed on the scanning electrodes(Y1 through Y2) every time the polarity of the holding voltages is reversed, so that the brightness of the picture images does not change before and after the reversing of the holding voltage polarity. In case an anti-ferroelectric liquid crystal(10c) is used as the liquid crystal, the refresh pulse voltages which cause transitions of the liquid crystal states between positive ferroelectric and negative ferroelectric states and do not cause the transition from an anti-ferroelectric state to the ferroelectric states are imposed on the scanning electrodes. <IMAGE>
