Abstract: A display device includes: a first active pattern on a light blocking pattern; a second active pattern at a same layer as that of the first active pattern; a first insulating pattern on the first active pattern; a second insulating pattern on the first active pattern, the second insulating pattern being spaced from the first insulating pattern, and having a first contact hole exposing the first active pattern; a first gate electrode on the first insulating pattern; a second gate electrode at a same layer as that of the first gate electrode, and overlapping with the second active pattern; a first etch stopper on the second insulating pattern, and having a second contact hole connected to the first contact hole; and a first electrode on the first etch stopper, the first electrode contacting the light blocking pattern and the first active pattern through the first and second contact holes.

Abstract: A display device includes a pixel circuit, a first insulating layer covering the pixel circuit, a first electrode disposed on the first insulating layer, a second electrode disposed on the first insulating layer and spaced apart from the first electrode in a first direction, and a light emitting element electrically connected to the first electrode and the second electrode and disposed between the first electrode and the second electrode. A recess is provided in a first region of the first insulating layer between the first electrode and the second electrode when viewed in a plan view, and a width of the recess in the first direction is greater than a length of the light emitting element in the first direction. The first electrode and the second electrode do not overlap the recess when viewed in a plan view.
