Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an EL display having an extended serving life. SOLUTION: The EL display includes anode electrodes 3R, 3G and 3B, a barrier ribs 4 arranged around the anode electrodes 3R, 3G and 3B so as to allow the anode electrodes 3R, 3G and 3B to expose to bottom surfaces thereof, hole injection layers 5R, 5G and 5B arranged on the surfaces of the anode electrodes 3R, 3G and 3B, including an associated body of a donor molecule and an acceptor molecule having a sodium ion trap function, wherein the sodium ion is 0.005 to 1 wt.% with respect to the solid part, polymer light emitting layers 8R, 8G and 8B arranged on the surfaces of the hole injection layers 5R, 5G and 5B, and cathode electrodes 11R, 11G and 11B arranged on upper parts of the polymer light emitting layers 8R, 8G and 8B.
