A light emitting device includes a substrate and a plurality of light emitting components. The substrate has a plurality of accommodation recesses. The light emitting components are disposed in the accommodation recesses. The light emitting components include a die, a wavelength converting colloid, and a rooflike optic component apiece. The die can emit light and are disposed in accommodation recess. The die is perpendicularly projected onto the substrate to form a first orthogonal projection region. The wavelength converting colloid fills the accommodation recess and covers the die. The wavelength converting colloid has a convex surface. The rooflike optic component is disposed on the convex surface. The rooflike optic component is perpendicularly projected onto the substrate to form a second orthogonal projection region. The area of the first orthogonal projection region is less than the area of the second orthogonal projection region.

A display device include: a first light emitting element disposed in a first pixel area, a second light emitting element disposed in a second pixel area spaced apart from the first pixel area, a first color conversion layer disposed on the first light emitting element, a second color conversion layer disposed on the second light emitting element, a first color filter layer covering the first color conversion layer, a second color filter layer covering the second color conversion layer, and a third color filter layer disposed in a first non-light emitting area between the first pixel area and the second pixel area. The third color filter layer is configured to selectively transmit a color light different from color lights selectively transmitted by the first color conversion layer and the second color conversion layer.

Provided is a display device including a light emitting element layer disposed on a substrate, a thin-film encapsulation layer disposed on the light emitting element layer, a counter substrate facing the substrate, a color filter layer disposed on a surface of the counter substrate and having light transmitting areas and a light blocking area defined, a wavelength conversion layer disposed on the color filter layer, and a filling layer disposed between the wavelength conversion layer and the thin-film encapsulation layer, wherein the wavelength conversion layer includes, a bank overlapping the light blocking area, light transmitting members disposed between portions of the bank and spaced apart from each other, and organic layers spaced apart from each other with the bank interposed between the organic layers and covering the light transmitting members, and lower surfaces of the organic layers and a lower surface of the bank are disposed on a same layer.
