Abstract
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), includes: pixels of a first type in which when a halftone is displayed, supply of two or more kinds of data voltage 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 pixels of a second type in which when a halftone is displayed, supply of two or more kinds of data voltage 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. This makes it possible to achieve both an improvement in viewing angle characteristic and a reduction in flickers.
