摘要:
A liquid crystal panel (10) has a scanning line (Y) and a data line (X), a TFT (30) connected to the scanning line (Y) and the data line (X), a pixel electrode (32) connected to the TFT (30), and a rectangular opposite electrode (C) arranged oppositely to the pixel electrode (32) through a liquid crystal layer. The liquid crystal panel (10) is driven by a scanning line driving circuit (20) which supplies a scanning signal including a scanning period selecting at least one scanning line (Y), a data line driving circuit (22) which supplies a data signal to the data line (X), and an opposite electrode driving circuit (24) which changes a voltage supplied to the opposite electrode (C) corresponding to the selected scanning line in synchronization with the scanning period, and inverts the polarity of a voltage applied to the liquid crystal layer.
