Patent ID: 8253132

Claim:
A bottom emission type organic electroluminescent panel equipped with an electroluminescent element comprising an anode and a cathode on a substrate and at least one organic layer between the anode and the cathode, wherein the electroluminescent panel comprises: a main emission area emitting light with a high luminance; and a non-emission area or a low emission area emitting light with a relatively lower luminance than the main emission area, the non-emission area or low emission area being located outside an edge portion of the main emission area, provided that an edge portion of a cathode forming area is arranged outside the edge portion of the main emission area by limiting the main emission area to a smaller size than the cathode forming area, wherein, the anode lacks an insulating layer provided on a portion thereof which corresponds to the non-emission area or low emission area, and in an area of the anode which contacts the organic layer, the anode includes a first area having been subjected to a surface treatment to form the main emission area and an edge portion of the cathode forming area being arranged outside of the area having been subjected to the surface treatment, and the anode includes a second area which has not been subjected to the surface treatment and forms the non-emission area or low emission area.
