Abstract: A foldable display device is provided. The foldable display device may comprise a lower module, a display module on the lower module, a functional module on the display module, and a window module on the functional module. The display module may include a main region having a display area. The display module may include a lower inorganic encapsulation structure and an upper inorganic encapsulation structure directly contacting each other to form an inorganic-inorganic contact closed loop that substantially surrounds the display area in a plan view. The upper inorganic encapsulation structure may include at least three layers. Both of the upper inorganic encapsulation structure and the window module may be flexible.

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.
