摘要： A method of manufacturing a display device includes forming a light emitting structure on a substrate and forming a thin film encapsulation layer on the light emitting structure by chemical vapor deposition equipment. The forming the thin film encapsulation layer includes forming a first inorganic layer and performing a first plasma treatment on a first portion of the first inorganic layer which is opposite to a second portion of the first inorganic layer facing the light emitting structure. A first raw material in the forming the first inorganic layer includes hydrogen. A second raw material in the performing the first plasma treatment exclusively consists of hydrogen.

摘要： A display panel and a manufacturing method of a display panel are provided. A display panel includes: a base substrate in which a pixel area and a peripheral area adjacent to the pixel area are defined; a light emitting element located on the base substrate to overlap the pixel area, and configured to generate first light; a light control layer on the light emitting element; a color filter layer on the light control layer; and a capping layer contacting at least the light control layer and including silicon oxynitride (SiON), and the capping layer contains about 34 at % to about 41 at % of oxygen, and about 18 at % to about 25 at % of nitrogen. Luminous efficiency of the display panel may be increased while maintaining durability of the display panel.

摘要： 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.
