Abstract:
A liquid crystal display device in which pixels having a memory function are arranged includes: a display drive unit performing display driving by a driving method for obtaining halftone gray scales by setting plural frames as one cycle and temporarily changing gray scales of respective pixels within one cycle; and a pixel drive unit supplying a voltage having the same phase as, or the reverse phase to, a common voltage the polarity of which is inverted in a given cycle and applied to counter electrodes of liquid crystal capacitors to pixel electrodes of the liquid crystal capacitors. The pixel drive unit supplies an intermediate voltage between high- and low-voltage sides of the common voltage to the pixel electrodes of the liquid crystal capacitors at the time of transition from the supply of the voltage having the same phase to the supply of the voltage having reverse phase.
