Abstract: A stereoscopic display system includes a display panel and a liquid crystal shutter device. The liquid crystal shutter device includes a liquid crystal layer, a segment electrode, a counter electrode, an auxiliary electrode, an insulating layer, and a drive circuit. The drive circuit applies a drive voltage to the segment electrode in synchronization with a switching of a display of the display panel. Also, the drive circuit applies a voltage having an opposite phase to the voltage applied to the segment electrode to the auxiliary electrode.

Abstract: A plurality of pixel electrodes each forming one pixel are provided on a TFT substrate. A size of a pixel electrode located at a boundary portion between a non-rectangular active area and a frame region, which is an area outside the active area, is smaller than a size of a pixel electrode not located at the boundary portion. In such a configuration, a voltage is always applied to the plurality of pixel electrodes.
