A method of manufacturing a display device includes preparing a pixel circuit substrate including thin-film transistors and pixel electrodes respectively electrically connected to the thin-film transistors, forming a first deposition layer on the pixel circuit substrate using a first mask assembly, and forming a second deposition layer on the pixel circuit substrate using a second mask assembly. At least one of the first mask assembly and the second mask assembly includes a mask plate including an opening portion through which a deposition material passes and a covering portion that blocks a passage of the deposition material. The mask plate includes a protruding portion that protrudes from an edge of the covering portion toward a center region of the opening portion.
