Provided is a bottom emission type organic EL panel capable of preventing or delaying loss of light emission from an end portion of the light emission area and reduction of the light emission area in an organic EL element. This organic electro luminescence panel includes an organic electro luminescence element having at least one organic layer between an anode and a cathode arranged on a substrate. This panel has a main light emission area emitting light with a high luminance and a non-light emission area or a low light emission area emitting light with a lower luminance than the main light emission area, arranged outside the end portion of the main light emission area. By limiting the main light emission area to a smaller size than the cathode forming area, the end portion of the cathode forming area is arranged outside the end portion of the main light emission area.
