Abstract: A coating apparatus including an evaporation part, a thermal decomposition part, a deposition chamber, a vacuum pump, and a discharge pipe. The deposition chamber includes an upper portion, a lower portion facing the upper portion, and a sidewall portion connecting the upper portion and the lower portion to each other and including an inlet, first outlet, a second outlet, a third outlet and a fourth outlet. The discharge pipe includes a first auxiliary pipe connected to the first outlet and the second outlet, a second auxiliary pipe connected to the third outlet and the fourth outlet, an intermediate pipe connected to the first auxiliary pipe and the second auxiliary pipe, and a main pipe connected to the intermediate pipe. The vacuum pump is configured to discharge a portion of the monomer of the deposition material, which is not deposited, from the deposition chamber through the discharge pipe.

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.
