Abstract
Disclosed is an active matrix including a scanning signal line (16x), a data signal line (15x), and a first insulating film; and including, in a pixel region (101), a transistor (12a), a first pixel electrode (17a) connected to the data signal line via the transistor, a second pixel electrode (17b), a first capacitor electrode (87) electrically connected to the first pixel electrode (17a), and a second capacitor electrode (47) electrically connected to the second pixel electrode (17b), wherein the first capacitor electrode is provided in a same layer as the scanning signal line, the second capacitor electrode is provided in a same layer as the data signal line, and the first and second capacitor electrodes (87, 47) overlap each other by having the first insulating film sandwiched therebetween to form a capacitor between the first and second capacitor electrodes (87, 47). This allows reducing image sticking of a pixel electrode corresponding to a dark sub-pixel while holding down short-circuiting in a coupling capacitor formed part, in an active matrix substrate of a capacitively coupled pixel division mode.
