Abstract

A display device includes a plate-like substrate having a first surface and a second surface, pixel units on the first surface, and a power supply voltage feeder on the second surface. The power supply voltage feeder outputs first and second power supply voltages applicable to the pixel units. The second power supply voltage is lower in potential than the first power supply voltage. The display device includes a first wiring conductor electrically connecting the power supply voltage feeder and the pixel units and a second wiring conductor electrically connecting the power supply voltage feeder and the pixel units. At least one of the first or second wiring conductor includes a planar conductive portion covering the first surface. The planar conductive portion includes connectors connected to the power supply voltage feeder on at least two sides of the substrate.
