摘要： A display panel including a glass substrate having an opening area, and a display area at least partially surrounding the opening area; a thin film transistor on the display area including a semiconductor layer and a gate electrode; a display element electrically connected to the thin film transistor; a multi-layer including an insulating layer and a lower insulating layer. The insulating layer is between the glass substrate and the display element and the lower insulating layer is between the glass substrate and the insulating layer; and a thin-film encapsulation layer covering the display element including an inorganic encapsulation layer and an organic encapsulation layer. The multi-layer includes a first groove between the opening area and the display area. A first width of a portion of the first groove in the lower insulating layer is greater than a second width of a portion of the first groove in the insulating layer.

摘要： A display panel includes a peripheral region adjacent to a display region. The display region includes a hole peripheral region, and a recessed region is overlapped with the hole peripheral region. The display panel also includes a barrier layer with a penetrating opening overlapped with the recessed region, a circuit layer on the barrier layer and including a transistor and insulating layers, and a device layer including an organic light emitting area coupled to the circuit layer. In addition, a module hole is overlapped with the hole peripheral region and penetrates the base substrate, and a first groove is overlapped with the bole peripheral region and corresponds to a portion of the base substrate that is recessed from a top surface of the barrier layer and that encloses the module hole. The insulating layers include inorganic layers and an organic layer having side portions enclosing the module hole.

摘要： A display device capable of improving reliability (e.g., impact resistance) of a display panel having a through-hole, and a method of manufacturing a display device are provided. A display device includes: a camera module including a lens; a display panel including a through-hole overlapping the camera module on a plane; a window glass on the display panel; and a filling member in the through-hole and opposing each of the camera module and the window glass. A refractive index difference between an end portion of the filling member and the lens is about 0.7 or less, and a refractive index difference between another end portion of the filling member and the window glass is about 0.5 or less.

摘要： A display device includes a substrate, a switching element on the substrate, a pixel electrode disposed on the switching element and connected to the switching element, a light emitting layer on the pixel electrode, a common electrode on the light emitting layer, and a sealing portion on the common electrode. The sealing portion includes an organic layer, and at least one first composite inorganic layer disposed between the organic layer and the common electrode. The at least one first composite inorganic layer includes a first inorganic layer between the common electrode and the organic layer, and a second inorganic layer between the first inorganic layer and the organic layer. A refractive index of the first inorganic layer and a refractive index of the second inorganic layer are different from each other, and the first inorganic layer and the second inorganic layer contact each other.
