Abstract: A mask assembly includes a first mask having a first opening and at least one second mask disposed on the first mask, each at least one second mask including a deposition area having second openings, an inner area surrounding the deposition area, and an outer area having third openings which surround the margin area. A line defining the outer boundary of an inner surface which defines the first opening overlaps the inner area when viewed in plan.

Abstract: One or more embodiments include a display apparatus including an opening, an apparatus for manufacturing the display apparatus, and a method of manufacturing the display apparatus capable of reducing generation of gas or foreign matter.

Abstract: A display apparatus includes a first pixel and a second pixel arranged on a substrate and adjacent to each other; and each including a common layer and an opposite electrode each being provided as a body; a pixel-defining layer including openings respectively corresponding to the first pixel and the second pixel and defining emission areas; and a structural layer arranged on the pixel-defining layer and including an upper surface, a first lateral surface, and a second lateral surface. The first lateral surface is connected to the upper surface and has a slope tapered in a reverse direction. The second lateral surface is connected to the upper surface and has a slope tapered in a forward direction. Each of the common layer and the opposite electrode includes a discontinuous portion disconnected by the first lateral surface.

Abstract: A display apparatus includes: a substrate having a plurality of first group areas spaced apart from each other; a first pixel electrode and a second pixel electrode in each of the plurality of first group areas; a first intermediate layer on the first pixel electrode; a second intermediate layer on the second pixel electrode; an opposite electrode on the first intermediate layer and the second intermediate layer; and a plurality of first capping layers on the opposite electrode and spaced apart from each other to correspond to the plurality of first group areas.

Abstract: A display device includes: a substrate including a first display area and a second display area including a transmission area; first pixels in the first display area; and second pixels in the second display area, wherein a distance between a first sub-pixel from among the first pixels, the first sub-pixel being adjacent to a boundary area between the first display area and the second display area, and a second sub-pixel from among the second pixels, the second sub-pixel being adjacent to the boundary area, is set to a certain value.

Abstract: A mask assembly includes a mask and a blocking stick. The mask includes a pattern region formed therein with openings and extends in a first direction. The blocking stick is disposed under the mask and overlaps a first side portion of the mask. The mask further includes dummy opening regions and opening regions. The dummy opening regions are arranged in the first direction in the first side portion of the mask, and are formed therein with openings. The opening regions are arranged in the first direction in a second side portion which is opposite to the first side portion of the mask and correspond to the dummy opening regions, respectively. The number of the openings per a unit area in each of the dummy opening region and the opening region is smaller than the number of the openings per a unit area in the pattern region.

Abstract: A display device includes: a substrate having a component area, a main display area, and a peripheral area, the peripheral area surrounding the component area and the main display area; an auxiliary pixel group disposed in the component area and including an auxiliary subpixel pixel electrode, an auxiliary subpixel intermediate layer, and an auxiliary subpixel opposite electrode; and a main pixel group disposed in the main display area and including a main subpixel pixel electrode, a main subpixel intermediate layer, and a main subpixel opposite electrode, wherein the auxiliary subpixel opposite electrode extends in the component area to have a stripe shape and is connected to the main subpixel opposite electrode in the main display area.

Abstract: A display device includes: a substrate including a first display area and a second display area including a transmission area; first pixels in the first display area; and second pixels in the second display area, wherein a distance between a first sub-pixel from among the first pixels, the first sub-pixel being adjacent to a boundary area between the first display area and the second display area, and a second sub-pixel from among the second pixels, the second sub-pixel being adjacent to the boundary area, is set to a certain value.
