Abstract

A display device includes a substrate having at least two transmissive areas and a non-transmissive area disposed between the at least two transmissive areas; a subpixel in the non-transmissive area, the subpixel including a first electrode, a light emitting layer, and a second electrode; at least two spacers each in respective ones of the at least two transmissive areas; and at least two organic patterns on upper surfaces of respective ones of the at least two spacers.

Claims (26)

1 . A display device, comprising

a substrate having at least two transmissive areas and a non-transmissive area disposed between the at least two transmissive areas;

a subpixel in the non-transmissive area, the subpixel including a first electrode, a light emitting layer, and a second electrode;

at least two spacers each in a respective one of the at least two transmissive areas; and

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.

7 . The display device according to claim 5 , wherein the capping layer at least partially covers the upper surface of each of the at least two organic patterns and a side surface of each of the at least two spacers.

8 . The display device according to claim 6 , further comprising an inorganic passivation layer between the encapsulation layer and the capping layer.

9 . The display device according to claim 1 , further comprising a bank in each of the at least two transmissive areas, each of the at least two spacers being on a respective bank.

10 . The display device according to claim 9 , wherein each bank partially covers an edge of the first electrode such that each bank is absent on a central portion of the first electrode.

11 . The display according to claim 1 , wherein an upper surface of each of the at least two organic patterns has a same shape as an upper surface of each of the at least two spacers.

12 . The display device according to claim 1 , wherein upper surfaces of the at least two organic patterns and the at least two spacers have a cross shape.

13 . The display device according to claim 1 , wherein upper surfaces of the at least two organic patterns and the at least two spacers have a circular shape.

14 . The display device according to claim 1 , wherein upper surfaces of the at least two organic patterns and the at least two spacers have a rectangular shape.

15 . The display device according to claim 1 , further comprising an inorganic passivation layer on the second electrode and the at least two organic patterns such that the inorganic passivation layer at least partially covers upper surfaces and side surfaces of the at least two organic patterns.

16 . The display device according to claim 1 , wherein the second electrode is spaced apart from the at least two organic patterns.

17 . The display device according to claim 1 , wherein the second electrode includes an opening overlapped with at least a portion of one of the at least two transmissive areas.

18 . The display device according to claim 1 , wherein the second electrode includes a semi-transmissive metal material or an opaque metal material.

19 . The display device according to claim 1 , wherein the second electrode includes at least one of Ag or Mg.

20 . The display device according to claim 1 , further comprising an optical sensor disposed under the substrate,

wherein the optical sensor overlaps the at least two transmissive areas and the non-transmissive area.
