at least two organic patterns each on a respective upper surface of a respective one of the at least two spacers,
wherein the second electrode is not disposed on the at least two organic patterns.
2 . The display device according to claim 1 , wherein each spacer has an upper surface wider than a lower surface thereof.
3 . The display device according to claim 1 , wherein the at least two organic patterns include a material that enables desorption of a metal material.
4 . The display device according to claim 3 , wherein the at least two organic patterns include a photoisomerization material.
5 . The display device according to claim 1 , further including a capping layer over the subpixel and the at least two organic patterns.
6 . The display device according to claim 5 , further including an encapsulation layer on the capping layer.
