Abstract
In one embodiment, the liquid crystal shutter is equipped with a first liquid crystal panel in the OCB mode to control the transmissivity of the light entering into left eye and a second liquid crystal panel in the OCB mode to control the transmissivity of the light entering into right eye, and a drive portion to control the transmissivity. The drive portion applies a normal voltage of a normal drive in a pulse shape and a retention voltage having a pulse shape with lower frequency than the normal voltage or lower voltage than normal voltage to the first liquid crystal panel and the second liquid crystal panel. The drive portion switches between the normal drive and the retention drive while maintaining bend alignment state.
