ABSTRACT:
A liquid-crystal display apparatus includes a layer of liquid crystal. A matrix array is composed of scanning electrodes and signal electrodes. The scanning electrodes extend along a matrix row direction. The signal electrodes extend along a matrix column direction. Switching circuit elements are located at respective places where the scanning electrodes intersect with the signal electrodes. Pixel electrodes connected to the switching circuit elements are operative for controlling portions of the liquid-crystal layer respectively. A first device is operative for driving the scanning electrodes. A second device is operative for delaying a first video signal into a second video signal. A third device is operative for alternately selecting one out of the first video signal and the second video signal to generate a third video signal in response to the first video signal and the second video signal. A fourth device is operative for periodically inverting a polarity of the third video signal at a timing synchronous with alternately selecting by the third device to convert the third video signal into a fourth video signal. A fifth device is operative for feeding the fourth video signal to the signal electrodes.
