Abstract

Disclosed is a display device having a pixel including a pixel electrode, an electroluminescence layer over the pixel electrode, and an opposing electrode over the electroluminescence layer. The pixel electrode possesses: a first conductive layer including a conductive oxide containing indium and zinc; a second conductive layer over the first conductive layer, the second conductive layer containing silver; and a third conductive layer over the second conductive layer, the third conductive layer including a conductive oxide containing indium and tin. A thickness of the first conductive layer is equal to or more than twice a thickness of the third conductive layer and equal to or less than five times the thickness of the third conductive layer.
