ABSTRACT:
In order to suppress potential fluctuation by increases in wiring resistance and necessary current amount caused by increases in the size and resolution of a display area, a display area in which a plurality of EL devices and a plurality of pixel circuits are disposed on a substrate is formed. Each EL device is disposed between a lower pixel electrode and an upper transparent electrode on the substrate. The pixel electrode is electrically connected to a power supply line through the pixel circuit, and the transparent electrode is electrically connected to a common voltage line through a contact hole. The power supply line and the common voltage line are disposed parallel to each other at a periphery of the display area, and the power supply line is divided into two lines disposed on both sides of the contact hole. Alternatively, the power supply line is disposed on one side of the contact hole, and the common voltage line is disposed on the other side of the contact hole with a width larger than that of the contact hole.
