Abstract: A color-converting substrate includes a color-converting part including a wavelength-converting particle configured to change a wavelength of an incident light to emit a light having a color different from the incident light, a color filter pattern filtering the light emitted from the color-converting part, and a light-reflective layer disposed between the color-converting part and the color filter pattern to selectively reflect a light having a wavelength same as the wavelength of the incident light.

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.
