Abstract
The liquid crystal display device has at least a liquid crystal panel, a signal line driver for driving signal lines in the liquid crystal panel, and a scanning line driver for driving scanning lines. To prevent waveform distortion due to a high output impedance of the signal line driver from causing adverse effects on a displayed image, a control means is provided which causes display signals to be written to pixel electrodes in the liquid crystal panel so as to avoid amplitude variation periods of the display signals. According to a preferred embodiment, the control means consists of a display signal delay circuit, a scanning signal delay circuit, and a display timing controller that control the signal line driver and the scanning line driver.
