摘要： Common signals VCOM during a black voltage writing period are set to be larger than common signals VCOM during a video writing period. The common voltage signals VCOM is VmH or VmL during the black voltage writing periods. The common voltage signals VCOM is VcH or VcL during video writing periods and video holding periods. The polarity of the common voltage signals VCOM is inverted alternately from frame to frame. A backlight is extinguished in the black voltage writing period.

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.
