Bottom emission type organic electroluminescent panel

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;
• a low emission area emitting light with a relatively lower luminance than the high luminescence of the main emission area, the low emission area being located outside an edge portion of the main emission area,
• wherein the anode extends outside of the main emission area on a same side of the substrate as the electroluminescent element to form an anode take-out part, the anode take-out part not being superposed by a portion of the cathode, and
• wherein an edge portion of a cathode forming area is arranged outside the edge portion of the main light emission area by limiting the main emission area to a smaller size than the cathode forming area,
• wherein the organic layer has an uncovered area which overlaps with a part of the anode take-out part, the area having a larger layer thickness of the organic layer than another part of the organic layer that is in the main emission area;
• and
• wherein a part of the cathode is formed so as to overlap on at least a part of the area having a larger layer thickness.
