LIQUID CRYSTAL DISPLAY DEVICE |
摘要 |
A liquid crystal display device (100) includes: a liquid crystal display panel (10); a scan line driving circuit (20) that supplies a scan signal voltage to each pixel (Px) via a corresponding scan line (11); a signal line driving circuit (30) that supplies a display signal voltage to each pixel via a corresponding signal line (12); and a display control section (40) including a polarity reversal driving switching section (41) that switches a mode of polarity reversal of the display signal voltage. In a case where the polarity reversal driving switching section switches the polarity reversal mode in transition from a first vertical scan period to a second vertical scan period immediately succeeding the first vertical scan period, the display control section is capable of making a largeness of a display signal voltage supplied in the second vertical scan period different from its original largeness only for a pixel group included in the plurality of pixels to which display signal voltages that have the same polarity in both the first and second vertical scan periods are supplied. |

1. A liquid crystal display device, comprising:
a liquid crystal display panel having a plurality of pixels arranged in a matrix which has a plurality of rows and a plurality of columns, the liquid crystal display panel having a plurality of scan lines extending in a row direction and a plurality of signal lines extending in a column direction; a scan line driving circuit that supplies a scan signal voltage to each of the plurality of pixels via a corresponding scan line; a signal line driving circuit that supplies a display signal voltage to each of the plurality of pixels via a corresponding signal line; and a display control section including a polarity reversal driving switching section that switches a mode of polarity reversal of the display signal voltage, wherein in a case where the polarity reversal driving switching section switches the mode of polarity reversal of the display signal voltage in transition from a first vertical scan period to a second vertical scan period immediately succeeding the first vertical scan period, the display control section is capable of making a largeness of a display signal voltage supplied in the second vertical scan period different from its original largeness only for a pixel group included in the plurality of pixels to which display signal voltages that have the same polarity in both the first and second vertical scan periods are supplied. |
