摘要： A liquid crystal shutter includes a first support substrate having a first electrode and a second support substrate having a second electrode opposite to the first electrode. A liquid crystal layer is sandwiched between the first and second electrodes so as to have a switching region. The switching region becomes a bend alignment state from a splay alignment state when a voltage is applied to the liquid crystal layer. A nucleus region formation portion is arranged on the first support substrate to form a nucleus region in the switching region corresponding to the nucleus region formation portion in the liquid crystal layer, in which the splay alignment is more stable than in the switching region.

摘要： 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.
