Abstract

Official abstract text for this publication.

A display device includes a substrate including pixels, a first electrode and a second electrode spaced apart from each other, light emitting elements disposed between the first electrode and the second electrode, an insulation layer disposed on the light emitting elements, a first bank overlapping the first electrode and the second electrode, a first area overlapping the first bank, and a second area excluding the first area, wherein the insulation layer includes an opening exposing the first area.

First claim

Opening claim text (preview).

What is claimed is: 1 . A display device comprising: a substrate including pixels; a first electrode and a second electrode spaced apart from each other; light emitting elements disposed between the first electrode and the second electrode; an insulation layer disposed on the light emitting elements; a first bank overlapping the first electrode and the second electrode; a first area overlapping the first bank; and a second area excluding the first area, wherein the insulation layer includes an opening exposing the first area. 2 . The display device of claim 1 , wherein an edge of the opening of the insulation layer is parallel to an upper surface of the substrate. 3 . The display device of claim 1 , wherein the opening of the insulation layer exposes the second electrode. 4 . The display device of claim 3 , wherein an edge of the opening of the insulation layer and an upper surface of the second electrode are disposed on a same surface. 5 . The display device of claim 1 , further comprising a second bank disposed at boundaries of the pixels, wherein an edge of the opening of the insulation layer and an upper surface of the second bank are disposed on a same surface, and at least one of a color filter layer and a conversion layer overlaps at least one of the pixels. 6 . The display device of claim 1 , further comprising a first contact electrode contacting the first electrode and an end of the light emitting element; and a second contact electrode contacting the second electrode and another end of the light emitting element. 7 . The display device of claim 6 , wherein a thickness of the first contact electrode in the first area is greater than a thickness of the second contact electrode in the first area. 8 . The display device of claim 6 , wherein a thickness of the second contact electrode in the first area is less than a thickness of the second contact electrode in the second area. 9 . The display device of claim 6 , wherein the opening of the insulation layer exposes the first contact electrode. 10 . The display device of claim 9 , wherein an edge of the opening of the insulation layer and an upper surface of the first contact electrode are disposed on a same surface. 11 . The display device of claim 6 , wherein the opening of the insulation layer exposes the second contact electrode. 12 . The display device of claim 6 , wherein the insulation layer includes a first insulation layer disposed between the first contact electrode and the second contact electrode; and a second insulation layer disposed on the first contact electrode and the second contact electrode. 13 . The display device of claim 12 , wherein the opening of the first insulation layer exposes the first contact electrode. 14 . The display device of claim 12 , wherein the opening of the second insulation layer exposes the second contact electrode. 15 . The display device of claim 12 , wherein the opening of the second insulation layer exposes the second electrode. 16 . The display device of claim 12 , wherein an edge of the opening of the first insulation layer and an edge of the opening of the second insulation layer are disposed on a same surface. 17 . The display device of claim 12 , wherein an edge of the opening of the first insulation layer and an edge of the opening of the second insulation layer are parallel to an upper surface of the substrate. 18 . The display device of claim 6 , wherein the opening of the insulation layer exposes the first contact electrode and the second contact electrode. 19 . The display device of claim 18 , wherein an edge of the opening of the insulation layer, an upper surface of the first contact electrode, and an upper surface of the second contact electrode are disposed on a same surface. 20 . The display device of claim 18 , wherein a thickness of the first contact electrode in the first area is less than a thickness of the first contact electrode in the second area, and the thickness of the first contact electrode in the first area is substantially same as a thickness of the second contact electrode in the first area.
