Abstract
At least one embodiment of a liquid crystal display device including: pixels each of which includes a plurality of sub-pixels; and scanning signal lines provided in a display area, the scanning signal lines being divided into groups each of which includes a plurality of scanning signal lines, the groups being sequentially selected, the polarity POL of signal electric potentials being inverted when the selected group is changed from a preceding group to a succeeding group which is selected immediately after the preceding group, a plurality of (for example, two) dummy scanning periods being inserted between a horizontal scanning period corresponding to last horizontal scanning (scanning of G) in the preceding group and a horizontal scanning period corresponding to first horizontal scanning (scanning of G) in the succeeding group, and a scanning signal line (for example, G) which belongs to a group selected after the preceding group being subjected to dummy scanning during each dummy scanning period so as to be made active for a predetermined period of time, and then deactivated. With the arrangement, it is possible to suppress horizontal-shaped unevenness that occurs in a case where block inversion driving is carried out in a multi-pixel mode liquid crystal display device.
