A light emitting device includes a first pixel that includes a first light-emitting structure, a first color conversion layer on the first light-emitting structure, and a first multi-layered filter on the first color conversion layer, and a second pixel that includes a second light-emitting structure, a second color conversion layer on the second light-emitting structure, and a second multi-layered filter on the second color conversion layer. Each of the first and second multi-layered filters includes at least one stack including a first film and a second film. The first multi-layered filter outputs light of a wavelength band that is different from a wavelength band of light output from the second multi-layered filter. The first multi-layered filter reflects light not output back into the first pixel and the second multi-layered filter reflects light not output back into the second pixel.
