Abstract
Various types of electrode structures were investigated to obtain the threshold voltage difference that allows for the elimination of the off-axis gamma shift in a multi-domain vertical-alignment liquid crystal cell. The threshold voltage difference can be obtained simply by changing the width of the electrodes or the distance between the electrodes in a two-terminal cell. It can also be obtained by applying a different bias voltage to a three-terminal (3T) cell. The advantages and disadvantages of three types of cell structures were compared. By optimizing the electrode structure of a 3T cell with the top electrode grounded, a 2.9 V threshold voltage difference was experimentally obtained.
