Abstract: A deposition apparatus may include a chamber, a crucible in the chamber, a cover part covering the crucible, and 2n nozzles (where ‘n’ is a positive integer number) protruding from the cover part and arranged in a first direction. Among the 2n nozzles, a distance between a n-th nozzle and a (n+1)-th nozzle may be greater than a distance between a (2n−1)-th nozzle and a 2n-th nozzle.

Abstract: A method of manufacturing a display apparatus includes: preparing a substrate including a display area and a sensor area arranged in the display area; forming first counter electrodes on the substrate so that the first counter electrodes are spaced apart from one another in the sensor area to have a first pattern; depositing second counter electrodes having a second pattern different from the first pattern to be spaced apart from one another in the sensor area; and arranging a component to correspond to the sensor area.

Abstract: A display device according to an embodiment may include a base substrate, a circuit layer, a light emitting element layer, and a module hole. The light emitting element layer may include a first electrode, a light emitting layer, and a second electrode. The second electrode may include a first portion that is not overlapped with the module hole and has a first thickness and a second portion between the module hole and the first portion and having a thickness that gradually increases in a direction toward the first portion. Thus, the display device may improve in durability in a hot and humid environment.
