  • Patent number: 10311804
    Abstract: In particular case second vertical scanning period includes a write period in which a first potential difference V1 is to be given to an upper electrode and a lower electrode. In another particular case, the second vertical scanning period includes a write period in which a second potential difference V2 being greater than the first potential difference V1 is given to the upper electrode and the lower electrode. In the former write period, substantially the same potential as that of a counter electrode is given to the upper electrode, and a different potential from that of the counter electrode is given to the lower electrode. In the latter write period, substantially the same potential as that of the counter electrode is given to the lower electrode, and a different potential from that of the counter electrode is given to the upper electrode.

  • Publication number: 20190164511
    Abstract: In a liquid crystal display device (100), each pixel row group is selected by a common scan signal voltage, each pixel row group including N pixel rows which adjoin one another in a column direction. Where two pixel rows which adjoin each other in a column direction and which are included in different pixel row groups are a first pixel row and a second pixel row, the first pixel row includes a pixel which has a pixel electrode (16) capacitively coupled with a gate bus line (12) which is associated with the second pixel row. When the first pixel row is included in the qth group, the second pixel row is included in the (q+1)th group. A scan signal voltage supplied to gate bus lines which are associated with the (q+1)th group switches from low to high before a scan signal voltage supplied to gate bus lines which are associated with the qth group switches from high to low.
