Abstract: Provided are a display device, a mask assembly, and an apparatus and a method for manufacturing the display device. The mask assembly includes: a mask frame; at least two mask sheets installed on the mask frame, each of the mask sheets including a plurality of openings; and at least two thin shielding plates installed on the mask frame such that the thin shielding plates are spaced apart from each other and shield a portion of the plurality of openings of each mask sheet, wherein one of the mask sheets and the thin shielding plates includes a shielding portion between the thin shielding plates spaced apart from each other, the shielding portion selectively blocking at least portions of the openings so as to form a deposition region having a shape other than a rectangle or a square.

Abstract: A display device, having relatively high side visibility and transmittance, includes a first substrate having a plurality of red, green, and blue pixel regions; a lower electrode disposed on the red, green, and blue pixel regions; and an upper electrode disposed on the red, green, and blue pixel regions. The upper electrode is insulated from the lower electrode, and includes a plurality of upper branch electrodes disposed on the lower electrode. A width and height of the upper branch electrode in at least one of the red, green, and blue pixel regions are respectively different from a width and a height of the upper branch electrode in another of the red, green and blue pixel regions.
