Abstract
The authors propose a method to control the viewing angle of a liquid crystal panel by electrically tilting the liquid crystal without incurring either an increase in cost from additional panels, or a decrease in transmittance by pixel division. Instead, an additional electrode is introduced to the top substrate of a fringe-field switching panel for the tilt control of the liquid crystal. We found that, without any loss of on-axis display performances, the viewing angle with a contrast ratio of over 10:1 can be switched between ±70 and ±10° along the azimuthal direction perpendicular to the rubbing angle by applying a small vertical bias voltage.
