Abstract
An organic electroluminescent element has at least one pair of electrodes including an anode and a cathode and one or more organic functional layers between the anode and the cathode that are in a pair. The organic electroluminescent element includes an organic functional layer that exists as a continuous phase over an entire display area and includes an at least one light emitting compound with a concentration gradient in an in-plane direction and in a thickness direction of the organic functional layer.
