摘要： According to an embodiment of the present invention, there is provided a display that includes a plurality of pixel circuits, a scanner, and a drive interconnect. The plurality of pixel circuits are arranged in a matrix and each includes at least one transistor of which the conduction state is controlled through the reception of a drive signal to a control terminal. The scanner outputs a drive signal to the control terminals of the transistors included in the pixel circuits. The drive interconnect is connected to the control terminals of the transistors in the pixel circuits in common and allows transmission of a drive signal output by the scanner. The drive interconnect includes a configuration that averages signal delay due to interconnect resistance differences dependent upon the distance from a drive signal output terminal of the scanner.
