Abstract: A display device includes a pixel unit configured to emit light. The display device includes a lower substrate, a plurality of light-emitting devices, an upper substrate, a bank layer, and a functional layer. The plurality of light-emitting devices is on the lower substrate. The upper substrate is on the lower substrate. The plurality of light-emitting devices is between the upper substrate and the lower substrate. The bank layer is on one surface of the upper substrate facing the lower substrate. The bank layer includes partition walls defining a central opening corresponding to the pixel unit and an auxiliary opening adjacent to the central opening. The functional layer fills the central opening. The functional layer includes at least one of quantum dots and scattering particles. The plurality of light-emitting devices includes a main light-emitting device overlapping the central opening and an auxiliary light-emitting device overlapping the auxiliary opening.
