PROBLEM TO BE SOLVED: To provide an organic EL display panel with little brightness unevenness by adoption of an auxiliary wiring structure with small man-hour increase. SOLUTION: Of a top-face emission type display panel with an organic EL substrate and a color filter substrate bonded together, the organic EL substrate has a transparent substrate, a TFT+flattened resin layer, a reflective electrode layer, an organic EL layer and a transparent electrode laminated in that order, the reflective electrode layer consists of a reflective electrode, an auxiliary wiring, and an insulating film with openings at a position corresponding to a light-emitting part on the reflective electrode and on the auxiliary wiring. The auxiliary wiring is provided so as to be connected from one end of a screen to the other, has a shadow mask with a reverse tapered cross section so as its bottom face to be in contact with the auxiliary wiring inside the opening, the organic EL layer on the reflective electrode layer is formed so as to cover the reflective electrode fitted inside the opening at a position corresponding to the light-emitting part of the insulating film, and the transparent electrode covers the organic EL film formed so as to cover the reflective electrode and the insulating film in its periphery to be connected with the auxiliary wiring.
