Abstract
An organic light emitting diode, which is a top emission-type, is configured so that at least the following are laminated on the substrate: a reflective layer including a metal material; an anode conductive layer including a transparent conductive material; an organic EL layer having a light emitting layer which contains an organic light emitting material; and a cathode conductive layer in which a semi-transmissive metal layer and a transparent conductive layer including a transparent conductive material are laminated. On the surface of the semi-transmissive metal layer that is in contact with the transparent conducive layer side, a two-dimensional lattice structure is formed in which a plurality of protrusions are arranged periodically and two-dimensionally.
