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.
