    Abstract: A method of fabricating a deposition mask includes forming a wrinkle pattern in a mask rib region and including grooves by partially etching a front surface of a silicon substrate, forming a first photoresist pattern including first openings on a front surface of the silicon substrate in each of cell areas, growing a first plating film covering the grooves of the wrinkle pattern and a second plating film covering first openings of the first photoresist pattern, removing the first photoresist pattern, forming a second photoresist pattern in outer frame areas on a rear surface of the silicon substrate, and exposing a rear surface of metal mask ribs formed with the first plating film and a rear surface of a mask membrane formed with the second plating film by partially etching the rear surface of the silicon substrate using the second photoresist pattern.

    Abstract: A display device includes a display area including multiple pixels and a separator extending around the pixels, and a peripheral area located around the display area and including a scan driver and an electrostatic element part. Each pixel includes a pixel electrode, a light emitting auxiliary layer, and a common electrode. The light-emitting auxiliary layer is disconnected at the separator between neighboring pixels. The electrostatic element unit includes a first voltage line electrically connected to the scan driver, and multiple electrostatic elements electrically connected to the first voltage line. Multiple contact holes overlap the first voltage line located in the electrostatic element unit, and an insulating layer is located in the contact holes.

    Abstract: A display device includes pixels including a light emitting area and a non-light emitting area; light emitting elements disposed in the light emitting area; and a bank disposed in the non-light emitting area. The bank includes an opening overlapping the light emitting area in a plan view; a first area spaced apart from the opening; and a second area surrounding the opening and the first area, and a thickness of the second area is greater than a thickness of the first area.

    Abstract: A display device includes a substrate, a display element layer disposed on a first surface of the substrate and including a light emitting element that emits light, and a pixel circuit layer disposed on the display element layer and including a transistor electrically connected to the light emitting element. The display element layer includes a first contact electrode electrically connected to a first end of the light emitting element, and a second contact electrode electrically connected to a second end of the light emitting element. The pixel circuit layer includes a reflective layer disposed on the display element layer and overlapping the light emitting element. One of the first contact electrode and the second contact electrode is electrically connected to the transistor. The reflective layer reflects the light emitted from the light emitting element toward a second surface of the substrate.
