A liquid crystal display device of the present invention has a vertical scanning period in which the polarity of a display signal is positive and a vertical scanning period in which the polarity of a display signal is negative. 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.

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.

In a liquid crystal display device according to one embodiment of the present invention, when the polarities of the source signal voltages do not change over a plurality of horizontal scanning periods, the image write pulse of the gate signal supplied to a gate bus line that corresponds to pixels along the jth row rises before the source signal voltages change to values that correspond to pixels along the jth row. Next, the image write pulse of the gate signal supplied to a gate bus line that corresponds to pixels along the jth row falls, and then the image write pulse of the gate signal supplied to a gate bus line that corresponds to pixels along the kth row (j≠k) rises. The polarities of the storage capacitor signal voltages applied to storage capacitor bus lines that correspond to sub-pixels of pixels along the jth row are inverted after the image write pulse of the gate signal supplied to a gate bus line that corresponds to pixels along the kth row rises.

In one embodiment of the present invention, a large-screen or high-definition LCD is provided with its display quality improved significantly by reducing the viewing angle dependence of γ characteristic. Each pixel includes first and second subpixels, to which different voltages are applicable. The device further includes electrically independent storage capacitor trunks, each being electrically connected to the respective storage capacitor counter electrodes of either the first or second subpixels through storage capacitor lines. One vertical scanning period (V-Total) of an input video signal is divided into at least two subframes, in each of which a display signal voltage is written on each pixel. Two consecutive vertical scanning periods of the input video signal include a sequence in which the display signal voltage is written at the same polarity in two consecutive subframes and then has its polarity inverted in the next subframe. A storage capacitor counter voltage has, in each subframe, a first waveform, oscillating 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), and a second waveform, defined such that the effective value of the CS voltage storage capacitor counter voltage has a predetermined constant value every predetermined number of consecutive vertical scanning periods of the input video signal. Between two subframes in which the polarity of the CS voltage is inverted, the first waveforms of the CS voltage storage capacitor counter voltages have a phase difference of 180 degrees.
