摘要： Each pixel includes first and second subpixels with different luminances. Each subpixel includes a liquid crystal capacitor and a storage capacitor. The storage capacitor counter electrodes of the subpixels (such as those of the first subpixel of an arbitrary pixel and the second subpixel of a vertically adjacent pixel) are electrically independent. A storage capacitor counter voltage supplied through each storage capacitor trunk has a first period (A) with a first waveform and a second period (B) with a second waveform within one vertical scanning period (V-Total) of an input video signal, where V-Total=A+B. The first waveform oscillates between first and second voltage levels in a first cycle time PA, which is an integral number of times, and at least twice, as long as one horizontal scanning period (H). The second waveform is defined such that the effective value of the storage capacitor counter voltage has a predetermined constant value every predetermined number of (but 20 or less) consecutive vertical scanning periods. Thus, the viewing angle dependence of the γ characteristic can be reduced.

摘要： A liquid crystal display device according to the present invention includes a plurality of pixels, each including first and second subpixels. When a predetermined grayscale tone is displayed continuously through four or more consecutive even number of vertical scanning periods, the first and second subpixels have different luminances in at least two of the even number of vertical scanning periods, first polarity periods that are included in the vertical scanning periods and that maintain a first polarity are as long as second polarity periods that are also included in the vertical scanning periods and that maintain a second polarity for each of the first and second subpixels, and in each of the first and second polarity periods, the difference between the average of effective voltages applied to the liquid crystal layer of the first subpixel and that of effective voltages applied to the liquid crystal layer of the second subpixel is substantially equal to zero.

摘要： A color filter of the present invention includes a large number of colored layers of a plurality of colors regularly arranged together. The color filter is such that xWH−0.05≦xB≦xWH+0.05 and yWH−0.05≦yB≦yWH+0.05 or xWH−0.10≦xB≦xWH and yWH−0.10≦yB≦yWH is satisfied, where (xWH, yWH) is the chromaticity in the CIE 1931 chromaticity diagram when the filter alone is irradiated with light to produce a white display, and (xB, yB) is the chromaticity in the CIE 1931 chromaticity diagram when the filter is irradiated with the same light while being interposed between a pair of polarization plates arranged in a crossed Nicols state each having a degree of polarization of 99.98% or more.
