Mask for depositing emission layer, method of manufacturing the mask, and display apparatus manufactured using the mask
In a mask for depositing an emission layer, the mask includes: a plurality of deposition areas corresponding to a plurality of display panels, wherein each of the plurality of deposition areas includes: a sensor area in which a plurality of grooves are arranged at regular intervals; and a main deposition area outside the sensor area to surround the sensor area, the main deposition area including a plurality of through-holes arranged at regular intervals to enable a deposition material to pass therethrough.
1 . A display apparatus comprising:
a substrate including an opening, a display area, and an intermediate area, the display area being outside the opening to surround the opening, and the intermediate area being between the opening and the display area;
a plurality of display elements over the display area, each of the plurality of display elements including a pixel electrode, an opposite electrode, and an emission layer between the pixel electrode and the opposite electrode;
a pixel defining layer on the substrate, having a pixel opening formed therethrough, wherein the emission layer is in the pixel opening; and
a dummy emission layer over the pixel defining layer in the intermediate area to be spaced apart from the emission layer, wherein an end of the dummy emission layer in a direction to the opening is not exposed by the opening.
2 . The display apparatus of claim 1 , further comprising a first functional layer over the display area and the intermediate area, between the pixel electrode and the emission layer in the display area, and including a first through-hole corresponding to the opening.
3 . The display apparatus of claim 2 , wherein an area of the first through-hole is equal to an area of the opening.
4 . The display apparatus of claim 2 , wherein an inner surface of the first through-hole and an inner surface of the opening form a continuous surface.
5 . The display apparatus of claim 1 , further comprising a second functional layer over the display area and the intermediate area, between the emission layer and the opposite electrode in the display area, and including a second through-hole corresponding to the opening.
6 . The display apparatus of claim 5 , wherein an area of the second through-hole is equal to an area of the opening.
7 . The display apparatus of claim 5 , wherein an inner surface of the second through-hole and an inner surface of the opening form a continuous surface.
8 . The display apparatus of claim 1 , wherein the dummy emission layer includes a plurality of dummy emission layers positioned around the opening.
9 . The display apparatus of claim 1 , wherein the dummy emission layer includes a plurality of dummy emission layers positioned around the opening, and an end of each of the dummy emission layers in the direction to the opening is not exposed by the opening.
10 . The display apparatus of claim 1 , further comprising a pixel-defining layer integrally formed as a single body over the display area and the intermediate area, and including a pixel opening that covers an edge of the pixel electrode and exposes the pixel electrode in the display area,
wherein an entire lower surface of the dummy emission layer is in contact with the pixel-defining layer.
11 . The display apparatus of claim 1 , wherein the display apparatus is one of a smartphone, a mobile phone, a navigation apparatus, a game console, a television (TV), a vehicle head unit, a notebook computer, a laptop computer, a tablet computer, a personal media player (PMP), a personal digital assistant (PDA), a center fascia of a vehicle, a dashboard of the vehicle, or a room mirror display of the vehicle.
