摘要： 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.

摘要： At least one embodiment of a liquid crystal display device including a display unit having scan signal lines divided into a plurality of groups which are successively selected. While the scan signal lines belonging to the selected group are successively scanned horizontally, signal potentials of the same polarity are successively supplied to a data signal line. The polarity of the signal potential is reversed between a preceding group and a subsequent group which are selected continuously. A plurality of dummy scan periods are inserted between the horizontal scan period corresponding to the last horizontal scan in the preceding group and the horizontal scan period corresponding to the first horizontal scan in the subsequent group. In each of the dummy scan periods, one of the scan signal lines which belong to the group selected after the preceding group is subjected to a dummy scan so that the scan signal line is maintained in an active state for a predetermined period and then deactivated so as to align the load state of a scan signal line drive circuit. This can reduce irregularities of the horizontal stripes when the data signal line is subjected to the block reverse drive.

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.
