Abstract: A display device includes a substrate on which a display area and a non-display area are defined, a first bank layer disposed on the substrate and defining openings in the display area, a second bank layer disposed on the first bank layer and including a side more protruded than a side of the first bank layer, light emitting elements disposed on the substrate and overlapping the openings, a first inorganic encapsulation layer disposed on the light emitting elements, an organic encapsulation layer disposed on the first inorganic encapsulation layer and the second bank layer, a second inorganic encapsulation layer disposed on the organic encapsulation layer; and a first dam disposed between the substrate and the second inorganic encapsulation layer in the non-display area, where an area of a first side of the first dam does not overlap the first inorganic encapsulation layer in a thickness direction of the substrate.

Abstract: A display device includes a substrate, a first electrode disposed on the substrate, an organic light-emitting layer disposed on the first electrode, a second electrode disposed on the organic light-emitting layer, an encapsulation layer disposed on the second electrode, and a touch layer disposed on the encapsulation layer. The encapsulation layer includes a first inorganic layer, a first organic layer, a second organic layer, and a second inorganic layer. The first inorganic layer is disposed on the second electrode, the first organic layer is disposed on the first inorganic layer, the second organic layer is disposed on the first organic layer and has a greater ring parameter than the first organic layer, and the second inorganic layer is disposed on the second organic layer.

Abstract: A manufacturing method of a display panel includes forming pixels in a display area of a substrate, and forming a metal wiring and a dam portion in a non-display area of the substrate, forming an encapsulation layer using an inorganic insulating material and an organic insulating material to cover the display area of the substrate and inspecting presence or absence of a remaining layer including the organic insulating material, which is formed in a remaining area of the encapsulation layer except for the display area, using a filter having a predetermined wavelength range.
