## Abstract

An interconnect is provided between data lines in plan view so as to include a line Cen extending along a Y direction. The data lines are disposed symmetrically with respect to the interconnect, and anode interconnects up to a pixel electrode are disposed symmetrically with respect to the interconnect. A power supply voltage of a pixel circuit is applied to the interconnect.
