摘要：A liquid crystal display device supplies an active scan signal to each scan line while skipping a portion of a plurality of the scan lines, per one horizontal scan period, in a direction of the m-th to the first scan lines, by a first scan line drive circuit, and supplies the active scan signal to each scan line while skipping the portion of the plurality of the scan lines, per one horizontal scan period, in a direction of the m+1-th to the 2m-th scan lines, by a second scan line drive circuit. Therefore, the liquid crystal display device synchronizes with a timing of supplying the active signal with the first scan line drive circuit and the second scan line drive circuit, and supplies a data signal whose polarity is inverted to a positive polarity potential and a negative polarity potential per one horizontal scan period, to a data line.
主权项：1. A liquid crystal display device comprising: a liquid crystal display panel that has a first region and a second region, wherein first to m-th scan lines are arranged in the first region, and m+1-th to 2m-th scan lines are arranged in the second region; a first data line group that includes p data lines intersecting with the scan lines which are arranged in the first region; a second data line group that includes p data lines intersecting with the scan lines which are arranged in the second region; pixels that are disposed to correspond to intersection of the scan lines and the data lines respectively, in each of the first region and the second region; a first scan line drive circuit that drives from the first to the m-th scan lines; a second scan line drive circuit that drives from the m+1-th to the 2m-th scan lines; a first data line drive circuit that drives the first data line group; and a second data line drive circuit that drives the second data line group, wherein the first scan line drive circuit supplies an active scan signal to each scan line, per one horizontal scan period, in a first direction of the first to the m-th scan lines, or in a second direction of the m-th to the first scan lines, the second scan line drive circuit supplies the active scan signal to each scan line, per one horizontal scan period, in a direction of the 2m-th to the m+1-th scan lines when the first scan line drive circuit supplies the active signal in the first direction, or in a direction of the m+1-th to the 2m-th scan lines when the first scan line drive circuit supplies the active signal in the second direction, the first data line drive circuit supplies data signals to the first data line group, synchronizing with a timing of supplying the active signal by the first scan line drive circuit, and the second data line drive circuit supplies data signals to the second data line group, synchronizing with a timing of supplying the active signal by the second scan line drive circuit, wherein when the first data line drive circuit supplies data signals to the first data line group, the active signal is sent to a first scan line of the first to the m-th scan lines in a first frame in the horizontal scan period and the active signal is sent to a second scan line of the first to the m-th scan lines in a second frame of the horizontal scan period immediately following the first frame, wherein the second scan line of first to the m-th scan lines is not adjacent to the first scan line of first to the m-th scan lines, and wherein when the second data line drive circuit supplies data signals to the second data line group, the active signal is sent to a first scan line of the 2m-th to the m+1-th scan lines in a first frame in the horizontal scan period and the active signal is sent to a second scan line of the 2m-th to the m+1-th scan lines in a second frame of the horizontal scan period immediately following the first frame, wherein the second scan line of 2m-th to the m+1-th scan lines is not adjacent to the first scan line of 2m-th to the m+1-th scan lines.
