Abstract
An organic electroluminescence display panel includes a plurality of organic electroluminescence elements, each comprised of a first display electrode, one or more organic functional layers including a light emitting layer made of an organic compound, and a second display electrode, laminated in order on a substrate, and a plurality of ramparts disposed between the organic electroluminescence elements on the substrate and protruding from the substrate. The display panel further includes a sealing film for covering the organic electroluminescence elements and at least both side surfaces of the ramparts, and an inorganic passivation film made of an inorganic material for covering the sealing film. The sealing film includes a top surface having an inclined surface which is inclined at an inclination angle smaller than a right angle in a region extending from a top edge of each rampart to a center peak of an adjacent one of the electroluminescence elements.
