An organic electroluminescence (EL) display panel including: a substrate; an insulating resin layer extending from an image display region to a peripheral region; an organic EL element array within the image display region; a sealing layer extending from the image display region to the peripheral region; and a sealing reinforcement layer, laminated in this order. The sealing layer includes first, second, and third sealing layers laminated in this order from the substrate, the first and third sealing layers being made of an inorganic material and the second sealing layer being made of a resin. In the outer peripheral portion of the sealing layer, the first and third sealing layers are in direct contact with each other and cover an outer end of the insulating resin layer. An outer end of the sealing reinforcement layer is outside the outer end of the insulating resin layer in plan view.
