Abstract
When a first data line becomes an H level and a second data line becomes an L level at the time that a scan line is at the H level, a first TFT is turned on and a second TFT is turned off. When the first TFT is turned on, a voltage higher than the voltage of a common electrode is applied to a pixel electrode, so that a pixel is displayed in black. When the first data line becomes the L level and the second data line becomes the H level at the time that the scan line is at the H level, the first TFT is turned off and the second TFT is turned on. When the second TFT is turned on, a voltage lower than the voltage of the common electrode is applied to the pixel electrode, so that a pixel is displayed in white.
