Abstract:
1. An active matrix substrate comprising: a substrate on which a transistor element, a pixel electrode, a scanning signal line, a data signal line, and a retention capacitor line are provided, the active matrix substrate further comprising at least two retention capacitor electrodes each facing the retention capacitor line via an insulating film so as to form a retention capacitance; and connection lines via which the at least two retention capacitor electrodes are connected with the pixel electrode, the retention capacitor line having at least one opening which penetrates the retention capacitor line in a direction perpendicular to a surface of the substrate, the at least two retention capacitor electrodes being provided for the retention capacitor line, the at least one opening being formed so as to include first regions facing respective second regions in which the at least two retention capacitor electrodes are provided, wherein the at least one opening is formed so as to include the first regions, the number of the at least one opening being one, and wherein the at least one opening is formed closer to a first side surface of the retention capacitor line than to a second side surface of the retention capacitor line, the first and second side surfaces being perpendicular to the direction in which the retention capacitor line is provided; and each of the at least two retention capacitor electrodes is formed, in a position where a corresponding one of the respective second regions is included, so that a region which extends from the corresponding one of the respective second regions to the first side surface is larger in area than a region which extends from the corresponding one of the respective second regions to the second side surface.
