When a pair of successive two vertical scanning periods is constituted by a first vertical scanning period and a second vertical scanning period, and when a target gradation level to be displayed in the first vertical scanning period is GL1, and a target gradation level to be displayed in the second vertical scanning period immediately after the first vertical scanning period is GL2, GL1 and GL2 being integers of 0 or more representing gradation levels, the liquid crystal display device includes a circuit (124) capable of supplying a display voltage corresponding to a gradation level to a pixel in the second vertical scanning period, the gradation level being expressed by GL2OD which satisfies a condition where |GL2OD-GL1| is larger than |GL2-GL1|, in the case where GL2 is different from GL1. The value of GL2OD when the polarity in the first vertical scanning period is positive and the polarity in the second vertical scanning period is negative is different from the value of GL2OD when the polarity in the first vertical scanning period is negative and the polarity in the second vertical scanning period is positive.

摘要： In one embodiment of the present invention, a gate driver creates a dummy insertion period in which the driver does not apply a gate on pulse to a scanning signal line immediately after the time of the inversion of a data signal. When a period from the time of the application of the gate on pulse to an odd numbered or even numbered scanning signal line to which the gate on pulse is applied previously to the time of the application of the gate on pulse to an even numbered or odd numbered scanning signal line to which the gate on pulse is applied later is set as an adjacent line writing time lag period for two scanning signal lines adjacent to each other, a CS control circuit allows the polarity of every CS signal to be reversed on the same cycle at least in the adjacent line writing time lag period. This makes it possible to provide a liquid crystal display device capable of offering high quality display in which unevenness in the display is suppressed without being affected by the blunt waveform of the data signal and the blunt waveform of a retention volume signal at the time of the inversion.

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 invention, a liquid crystal display device is disclosed, each pixel includes first and second subpixels, each of which includes a storage capacitor. Storage capacitor counter voltages applied independently to the storage capacitor counter electrodes of the first and second subpixels are varied within each vertical scanning period of the input video signal. As a result, each vertical scanning period of the input video signal includes a first subframe in which the first and second subpixels have luminances Y_SP1_A and Y_SP2_A, respectively, and a second subframe SFB in which the first and second subpixels have luminances Y_SP1_B and Y_SP2_B, respectively, where Y_SP1_A≠Y_SP2_A, Y_SP1_B≠Y_SP2_B, and Y_SP1_A≠Y_SP1_B or Y_SP2_A≠Y_SP2_B are satisfied. As a result, the viewing angle dependence of the γ characteristic can be reduced with the decrease in the transmittance of the liquid crystal display device minimized.
