An object of the present invention is to provide a technology for efficiently supplying electrons from an auxiliary electrode to a cathode via an electron transport layer and an electron injection layer. The solution of the present invention is an organic EL panel which includes a plurality of organic EL elements. The organic EL elements are arranged in a matrix, and each organic EL element has an anode, a light emitting layer, an electron transport layer, an electron injection layer, and a cathode in sequence. The electron transport layer, the electron injection layer, and the cathode are continuously formed throughout the plurality of organic EL elements. The organic EL panel is characterized by comprising an auxiliary electrode provided among the plurality of organic EL elements and configured to supply electrons to the cathode via the electron transport layer and the electron injection layer; and an insulating layer formed on a first opening portion inside which the light emitting layer is formed, and a s
