    Abstract: A display apparatus includes: a pixel electrode; a conductive bank layer defining a bank opening overlapping the pixel electrode, the conductive layer including a first conductive layer and a second conductive layer; an intermediate layer arranged in the bank opening and overlapping the pixel electrode; an opposite electrode arranged in the bank opening and disposed on the intermediate layer; and a first inorganic encapsulation layer disposed on the opposite electrode, filling the bank opening, and including an inorganic material. The first inorganic encapsulation layer includes a first portion overlapping the bank opening, and a second portion overlapping the conductive bank layer, and an upper surface of the first portion of the first inorganic encapsulation layer and an upper surface of the second portion of the first inorganic encapsulation layer are at a level higher than an upper surface of the conductive bank layer.

    Abstract: A display panel includes a base layer, a circuit layer, a light emitting element, a pixel defining film, an encapsulation layer, and a first dam. The base layer may include a display area and a non-display area adjacent to the display area. The encapsulation layer may include a first inorganic film, an organic film, and a second inorganic film. The first dam may be disposed between the first inorganic film and the second inorganic film, and outside the organic film. The first dam may overlap the non-display area and the pixel defining film on a plane. Therefore, in the display panel of an embodiment, the non-display area may be reduced.

    Abstract: A method of manufacturing a display device includes preparing an organic light-emitting device and forming an encapsulation member to encapsulate the organic light-emitting device. The forming of the encapsulation member includes forming a first inorganic encapsulation layer on the organic light-emitting device by providing a raw material gas on the organic light-emitting device, forming a first organic encapsulation layer by applying an organic material on the first inorganic encapsulation layer, and forming a second inorganic encapsulation layer on the first organic encapsulation layer. The raw material gas includes a nitrous oxide gas, a nitrogen gas, an ammonia gas, and a hydrogen gas, and a ratio of a sum of flow rates of the nitrous oxide gas and the nitrogen gas to a sum of flow rates of the ammonia gas and the hydrogen gas is about 1.1 or less.
