Abstract: A display device is capable of preventing damage to a signal line in a dehydrogenation process of a semiconductor layer and to a method of manufacturing the display device, the display device including: a substrate; at least one switching element on the substrate; a pixel electrode connected to the at least one switching element; a semiconductor layer on the substrate, the semiconductor layer providing a channel area of the at least one switching element; an insulating layer on the semiconductor layer; and a conductive layer connected to the semiconductor layer through a contact hole of the insulating layer. The insulating layer has a groove that overlaps the semiconductor layer and surrouds the conductive layer in the contact hole.

Abstract: A display apparatus includes: a first pixel, a second pixel, and a third pixel respectively configured to emit different colors; a first partition wall on a first light-emitting device of the first pixel; and a first color conversion layer corresponding to an emission area of the first pixel. The first partition wall has a first opening corresponding to the first light-emitting device and a first concave portion spaced apart from the first opening in a plan view. The first color conversion layer includes first quantum dots configured to convert incident light into first color light.
