Abstract: An electroluminescent device includes a lower structure including an emission area and a peripheral area, a flexible encapsulating multilayer, and a touch panel including a touch electrode. The emission area includes an electroluminescent unit including a lower electrode disposed directly on an insulating film, an intermediate film, and an upper electrode disposed on the intermediate film. The peripheral area includes an inorganic surface portion substantially surrounding the emission area, various terminals, and wires. A lower surface of the flexible encapsulating multilayer and an upper surface of the inorganic surface portion each include only one or more inorganic materials in direct contact with each other.

Abstract: In non-limiting example embodiments, an electroluminescent device may include a lower structure including an emission area, and an encapsulation structure located on the lower structure. The lower structure may include a window. The window may be a light transmitting region or a notch. The light transmitting region may be spaced apart from the emission area and completely or partially surrounded by the emission area in a plan view. The notch may be formed at one side of the lower structure and recessed inward in a plan view such that one side of the emission area substantially conforms to the notch.
