pixels in the display area on the substrate; a first dam in the first non-display area on the substrate, wherein the first dam includes an alignment hole; and a first alignment pattern in the first non-display area on the first dam, wherein the first alignment pattern at least partially overlaps the alignment hole in a plan view. ## Claims ### Claim 1 A display device comprising: a substrate including a hole area, a first non-display area surrounding at least a portion of the hole area, and a display area surrounding at least a portion of the first non-display area; pixels in the display area on the substrate; a first dam in the first non-display area on the substrate, wherein the first dam includes an alignment hole; and a first alignment pattern in the first non-display area on the first dam, wherein the first alignment pattern at least partially overlaps the alignment hole in a plan view. ### Claim 2 (depends on 1) The display device of claim 1, wherein the alignment hole overlaps one end of the first alignment pattern in the plan view. ### Claim 3 (depends on 1) The display device of claim 1, wherein the first dam has a ring shape surrounding the hole area. ### Claim 4 (depends on 3) The display device of claim 3, wherein the alignment hole has a ring shape surrounding the hole area. ### Claim 5 (depends on 1) The display device of claim 1, wherein each of the pixels includes a light-emitting element including a first electrode, a light-emitting layer on the first electrode, and a second electrode on the light-emitting layer, and the display device further comprises: a pixel defining layer covering a side portion of the first electrode. ### Claim 6 (depends on 5) The display device of claim 5, wherein the first dam includes, a first layer; a second layer on the first layer; and a third layer on the second layer and including a same material as the pixel defining layer. ### Claim 7 (depends on 6) The display device of claim 6, wherein the third layer of the first dam defines the alignment hole. ### Claim 8 (depends on 5) The display device of claim 5, further comprising: an input electrode on the light-emitting element, and wherein the first alignment pattern and the input electrode are in a same layer. ### Claim 9 (depends on 1) The display device of claim 1, further comprising: a second dam located in the first non-display area and spaced apart from the first dam in the plan view. ### Claim 10 (depends on 1) The display device of claim 1, further comprising: a second alignment pattern spaced apart from the first alignment pattern and at least partially overlapping the alignment hole in the plan view, and wherein the hole area is between the first alignment pattern and the second alignment pattern. ### Claim 11 (depends on 10) The display device of claim 10, wherein the alignment hole overlaps one end of the second alignment pattern in the plan view. ### Claim 12 (depends on 10) The display device of claim 10, further comprising: a third alignment pattern spaced apart from each of the first alignment pattern and the second alignment pattern in the plan view and at least partially overlapping the alignment hole in the plan view; and a fourth alignment pattern spaced apart from the third alignment pattern and at least partially overlapping the alignment hole in the plan view, and wherein the hole area is between the third alignment pattern and the fourth alignment pattern. ### Claim 13 (depends on 1) The display device of claim 1, wherein the substrate further includes a second non-display area surrounding at least a portion of the display area and in which a driver is located. ### Claim 14 (depends on 1) The display device of claim 1, further comprising: an insulating pattern in the first non-display area and spaced apart from the first dam in the plan view; and a metal pattern covering at least a portion of the insulating pattern. ### Claim 15 (depends on 14) The display device of claim 14, wherein one end of the metal pattern and the insulating pattern are spaced apart to form an undercut area. ### Claim 16 (depends on 14) The display device of claim 14, wherein the alignment hole and the metal pattern are spaced apart from each other in the plan view. ### Claim 17 A display device comprising: pixels in a display area; a component spaced apart from the pixels in a plan view; a dam surrounding at least a portion of the component, wherein the dam includes an alignment hole; and a first alignment pattern at least partially overlapping the alignment hole in the plan view. ### Claim 18 (depends on 17) The display device of claim 17, wherein the alignment hole overlaps one end of the first alignment pattern in the plan view. ### Claim 19 (depends on 17) The display device of claim 17, further comprising: a second alignment pattern spaced apart from the first alignment pattern and at least partially overlapping the alignment hole in the plan view, wherein the component is between the first alignment pattern and the second alignment pattern. ### Claim 20 An electronic device comprising: a substrate including a hole area, a first non-display area surrounding at least a portion of the hole area, and a display area surrounding at least a portion of the first non-display area; pixels in the display area on the substrate; a first dam in the first non-display area on the substrate, wherein the first dam includes an alignment hole; a first alignment pattern in the first non-display area on the first dam, wherein the first alignment pattern at least partially overlaps the alignment hole in a plan view; and a memory configured to store data information.
