Patent ID: 7119780

Claim:
A liquid crystal display comprising: a ferroelectric liquid crystal material configured to be held between a pair of electrode substrates and optical response thereof is asymmetric with respect to the polarity of a voltage applied; a signal applying section configured to apply to a pixel of said liquid crystal material an image signal which is updated for each of three or more fields forming one frame; and a polarity controller configured to reverse the polarity of the image signal in one frame period, said polarity controller being configured to apply the image signal of a first polarity for each field in a first one of two successive periods obtained by dividing the frame period, and to apply the image signal of a second polarity opposite to the first polarity for each subsequent field in a second one of the two successive periods, wherein the image signal applied for the field other than the last field in the second one of the two successive periods has a fixed amplitude, and the image signal applied for the last field in the second one of the two successive periods has an amplitude that depends on the amplitude of the image signal for the next frame.
