Abstract:
1. An active matrix substrate comprising: pixel regions; scanning signal lines extending in a row direction so as to cross the pixel regions corresponding thereto; data signal lines extending in a column direction; switching elements which are provided in the vicinity of corresponding intersections of the data signal lines and the scanning signal lines and each of which is connected to the data signal line and the scanning signal line forming the intersection in the vicinity of which the switching element is provided; storage capacitor wirings each of which is provided so as to correspond to a gap between pixel regions adjacent with each other in the column direction; and a pair of pixel electrodes in each pixel region, the pair of pixel electrodes forming storage capacitors with different ones of the storage capacitor wirings respectively, wherein: the pair of pixel electrodes provided in each pixel region adjacent with each other in the column direction is both connected to one of adjacent data signal lines via the switching element provided in the vicinity of an intersection of the one of the data signal lines and the scanning signal line crossing the pixel region, or to the other of the adjacent data signal lines via the switching element provided in the vicinity of an intersection of the other of the data signal lines and the scanning signal line crossing the pixel region; the intersections of the data signal lines and the scanning signal lines are grouped into A and B groups by alternately grouping intersections of a data signal line and the scanning signal lines into the A and B groups for every n adjacent intersections and grouping intersections adjacent in the row direction into different groups where n≧2; assuming that the adjacent data signal lines are referred to as first and second data signal lines; in a given pixel region, each of two pixel electrodes provided in a given pixel region is connected to the first data signal line via the switching element; and a pixel region adjacent to the given pixel region in the column direction is referred to as an adjacent pixel region, each of two pixel electrodes included in the adjacent pixel region is connected to a second data signal line of the adjacent pixel region via the switching element if (i) an intersection of the scanning signal line crossing the adjacent pixel region and the first data signal line and (ii) an intersection of the scanning signal line crossing the given pixel region and the first data signal line belong to the same one of the groups; and each of the two pixel electrodes included in the adjacent pixel region is connected to a first data signal line of the adjacent pixel region via the switching element if (i) the intersection of the scanning signal line crossing the adjacent pixel region and the first data signal line and (ii) the intersection of the scanning signal line crossing the given pixel region and the first data signal line belong to different ones of the groups.
