A display device includes a substrate, an emissive layer; a plurality of color converting layers that share the emissive layer, a barrier arranged on the emissive layer between the plurality of color converting layers, a first insulating layer provided between the plurality of color converting layers and the emissive layer and a second insulating layer provided between the first insulating layer and the plurality of color converting layers. The barrier spatially separates the plurality of color converting layers from each other and the first insulating layer has a plurality of first openings respectively corresponding to the plurality of color converting layers.
