The invention relates to a display device and a method of repairing the same. The display device includes pixel units 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. A plurality of light emitting devices are on the lower substrate. The upper substrate is on the lower substrate. A plurality of light emitting devices are 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 a partition wall defining a central opening corresponding to the pixel cell and an auxiliary opening adjacent to the central opening. The functional layer fills the central opening. The functional layer comprises 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 ove
