For organic EL panels with a hollow-sealed structure to meet the demand of flat or large displays, the inconvenience of contact of drying anent etc touching the organic EL elements in the sealed space is avoided. An organic EL panel includes a panel substrate, a light-emitting part with a plurality of organic EL elements having an anode, an organic layer and a cathode laminated on the panel substrate, and a sealing substrate configured to be bonded onto the panel substrate through an adhesive layer to seal the light-emitting part. The sealing substrate includes a supporting projection projecting toward the panel substrate. A supporting margin facing to the bottom face of the supporting projection is provided where the organic EL elements is not formed within a region of the light-emitting part on the panel substrate.
