DISPLAY DEVICE AND CAMERA

摘要

PROBLEM TO BE SOLVED: To suppress potential fluctuation due to increases in wiring resistance and necessary current amount caused by the extension of wiring length due to increases in size and resolution of a display area.

SOLUTION: A display area 6 in which EL devices and pixel circuits are disposed on a substrate 10 is formed. Each EL device is disposed between a lower pixel electrode and an upper transparent electrode on the substrate and the pixel electrode is electrically connected to a power supply line 1 through the pixel circuit. The transparent electrode is electrically connected to a common potential line through a contact hole. The power supply line and the common potential line are arranged in parallel to each other at the periphery of a display area. The power supply line is divided and disposed on both the sides of the contact hole, or the power supply line is disposed on one side of the contact hole and the common potential line is disposed on the other side of the contact hole so as to be extended wider than the width of the contact hole.
