    摘要： A display device includes first and second light emitting regions; first and second pixel electrodes in the first and second light emitting regions, respectively; a first organic layer in the first light emitting region, including first and second light emitting layers; a second organic layer in the second light emitting region, including a third light emitting layer; a common electrode on the first and second organic layers; a wavelength conversion pattern on the common electrode, overlapping the first organic layer, and wavelength-converting light of a first color into light of a second color, different from the first color; and a light transmitting pattern on the common electrode, overlapping the second organic layer. The third light emitting layer and one of the first and second light emitting layers emit light of the first color, and another one of the first and second light emitting layers emits light of the second color.
