Abstract:
1. A liquid crystal display device which carries out a single tone display with a change in pixel luminance during a single cycle composed of first to mth frame periods (m is an integer of 4 or more), comprising pixels and a source driver for supplying data voltages to each of the pixels, the pixels comprising: a pixel of a first type in which when a halftone is displayed successively, supply of two or more kinds of data voltage to apply a plurality of effective voltages of different magnitudes to the pixel of the first type during at least either the first to nth frame periods (n is an integer of 2 or more to m or less) or the (n+1)th to mth frame periods causes liquid crystal layers to produce rise responses during the first to nth frame periods and produce decay responses during the (n+1)th to mth frame periods; and a pixel of a second type in which when the halftone is displayed successively, supply of two or more kinds of data voltage to apply a plurality of effective voltages of different magnitudes to the pixel of the second type during at least either the first to nth frame periods or the (n+1)th to mth frame periods causes liquid crystal layers to produce decay responses during the first to nth frame periods and produce rise responses during the (n+1)th to mth frame periods.
