A controller in an intermediate inversion drive mode causes a source driver to alternate polarities of voltages applied to pixel electrodes connected to one of source signal lines per plural gate signal lines, and to apply the voltages so that a pair of the pixel electrodes, which are connected to one of the gate signal lines and to source signal lines adjacent to each other, are subjected to different voltage application in polarity from each other, the source driver alternating polarities of the voltages applied to the respective pixel electrodes for each frame. When the source driver, in the intermediate inversion drive mode, applies the voltages sequentially to the pixel electrodes connected to one of the source signal lines, the controller sets a longer voltage application period for the inverted electrode than for the equivalent electrode. |

1. A liquid crystal display device, comprising:
a liquid crystal display portion including source signal lines, gate signal lines and pixel electrodes connected to the source signal lines and the gate signal lines, the liquid crystal display portion configured to display an image in correspondence to an input image signal for each frame; a source driver configured to apply voltages in correspondence to the input image signal to the pixel electrodes through the source signal lines; a gate driver configured to output gate signals to the gate signal lines sequentially; and a controller configured to control the source driver and the gate driver to cause the source driver to apply a voltage to each of the pixel electrodes, for each gate signal line, in response to an output of each of the gate signals from the gate driver, the pixel electrodes connected to one of the source signal lines, wherein: the controller switches a drive mode of voltage application to the pixel electrodes between a first drive mode and a second drive mode, the controller causing an intermediate inversion drive mode to intervene between the first drive mode and the second drive mode, the controller in the intermediate inversion drive mode causes the source driver to alternate polarities of the voltages applied to the pixel electrodes connected to one of the source signal lines per plural successive adjacent gate signal lines, and to apply the voltages so that a pair of the pixel electrodes, which are connected to one of the gate signal lines and to source signal lines adjacent to each other, are subjected to different voltage application in polarity from each other, the source driver alternating polarities of the voltages applied to the respective pixel electrodes for each frame, an inverted electrode is a pixel electrode which is subjected to a different voltage in polarity from a voltage that another pixel electrode receives immediately before the inverted electrode, an equivalent electrode is a pixel electrode which is subjected to a common voltage in polarity with a voltage that another pixel electrode receives immediately before the equivalent electrode, and when the source driver, in the intermediate inversion drive mode, applies the voltages sequentially to the pixel electrodes connected to one of the source signal lines, the controller sets a longer voltage application period for the inverted electrode than for the equivalent electrode. |
