Abstract: A display device includes: a lower substrate; a display element on the lower substrate and including an emission layer; an upper substrate on the lower substrate with the display element therebetween, where the upper substrate includes a central area overlapping the display element and an adjacent area adjacent to the central area; a bank layer on a lower surface of the upper substrate facing the lower substrate, where a central opening overlapping the central area, an adjacent opening overlapping the adjacent area, and a connection portion connecting the central opening and the adjacent opening to each other are defined in the bank layer; a blocking layer overlapping the connection portion; and a functional layer including at least one selected from a quantum dot and a scatterer, where the functional layer fills the central opening in which a connection to the adjacent opening is blocked by the blocking layer.
