Abstract
Disclosed is a full color organic electroluminescence display device, comprising a substrate; a first electrode; organic film layers including red, green and blue emission layers and an electron transporting layer; and a second electrode. The thickness of the electron transporting layer, which is preferably formed as a common layer, is different in the red and green emission regions from that in the blue emission region so that the device has an excellent purity of color and improved luminous efficiency of red and green colors.
