PROBLEM TO BE SOLVED: To provide a display device having suitable display performance capable of preventing reduction of visibility caused by light reflection of a side wall of a partition wall covering a peripheral edge of a lower electrode pattern-formed at every pixel. SOLUTION: In the display device wherein a plurality of organic electroluminescent elements ELr, ELg, ELb sequentially laminating a lower electrode 21, emitting function layers 22r, 22g, 22b and an upper electrode 23 in that order, the partition wall 17 for separating each element having an opening 17a corresponding to respective organic electroluminescent elements ELr, ELg, ELb, are arranged on a substrate, and a black matrix 31 is arranged at an organic electroluminescent elements ELr, ELg, ELb light taking-out side, the side wall of the opening 17a of the partition wall 17 is formed in a tapered shape where its opening width is getting wider toward a light taking-out side of the organic electroluminescent elements ELr, ELg, ELb, and the black matrix 31 is arranged to cover a tapered upper edge R at least at one side forming the opening 17a of the partition wall 17.
