摘要： Each pixel includes first and second subpixels and two switching elements provided for those subpixels. Each subpixel includes a liquid crystal capacitor and a storage capacitor. The storage capacitor counter electrodes of the first and second subpixels are electrically independent. A storage capacitor counter voltage applied to each storage capacitor counter electrode by way of its associated storage capacitor line has a first period (A) with a first waveform during one vertical scanning period. The first waveform oscillates between multiple voltage levels in a first cycle time (PA) that is an integral number of times (and at least four times) as long as one horizontal scanning period (H). Each of the voltage levels has a flat portion with a duration TP. While the two switching elements are ON, a display signal voltage is applied to the respective subpixel electrodes and respective storage capacitor electrodes of the first and second subpixels. After the two switching elements have been turned OFF, voltages at the storage capacitor counter electrodes of the first and second subpixels change. And if an interval between a point in time when the two switching elements in ON state have just been turned OFF and a point in time when the storage capacitor counter voltage changes for the first time is βH, TP/4≦β

摘要： A color liquid crystal display device, configured to employ a pixel division method with two or more sub-pixels obtained by spatial or temporal division of one pixel in a division ratio, may include pixel formation portions configured to form a pixel with the sub-pixels; a drive circuit configured to provide each pixel formation portion with applied voltages based on a gradation value; a gamma correction part configured to correct a relationship between the gradation and luminance values of the pixel to be formed by that pixel formation portion; and a common electrode. The gamma correction part may suppress gradation dependence of chromaticity when the screen is viewed from a front and from an oblique direction. The gradation value may be determined by an area ratio of a first sub-pixel electrode to a second sub-pixel electrode and a difference in applied voltages between first and second auxiliary electrodes.

摘要： In one embodiment of the present application, a color liquid crystal display device is disclosed which can realize display having a high color reproducibility when a screen is viewed from an oblique direction as well as from a front direction, while improving a viewing angle dependence of γ-characteristics by employing a pixel division method. Gamma correction is carried out as follows independently for each R, G, and B with reference to R, G, and B correction tables so as to obtain a good color tracking. That is, the gamma correction is carried out such that chromaticity in the front view is shifted toward blue in an oblique hue correction range, which is determined by a pixel division ratio and the like, so as to reduce a shift of the chromaticity in the oblique view toward yellow in the oblique hue correction range, while maintaining a color balance in the other range (a gradation value range of 32 to 255 except for the oblique hue correction range). The present invention is suitable for a color liquid crystal display device employing the pixel division method.
