A display device includes a lower substrate (100) including first and second pixel areas and a light shielding area surrounding the first and second pixel areas, a light emitting structure disposed on the lower substrate, an upper substrate (200) disposed on the light emitting structure, a first color conversion layer (220) disposed in the first pixel area on a bottom surface of the upper substrate, a second color conversion layer (230) disposed in the second pixel area on the bottom surface of the upper substrate, first to third light shielding patterns (261, 262, 263) disposed in the light shielding area on the bottom surface of the upper substrate, a groove (264) defined on a bottom surface of at least one selected from the first to third light shielding patterns, and a spacer (250) disposed in the groove.
