A display device can include a plurality of pixels on a substrate; a plurality of sub pixels in each of the plurality of pixels; a first electrode at each of the sub pixels on the substrate; a first bank layer along a boundary of each of the first electrode on the substrate; a second bank layer along a boundary between the pixels on the first bank; a first emission layer extending across at least two first sub pixels among the plurality of sub pixels; and a second emission layer extending across at least two second sub pixels among the plurality of sub pixels, the second emission layer being adjacent to the first emission layer in a first direction, in which the first and second emission layers are configured to emit a light of a same color.
