Abstract: A display panel includes a light emitting element and an encapsulation layer on the light emitting element. The encapsulation layer covers the light emitting element. The encapsulation layer includes a plurality of polymer layers including a block copolymer. The plurality of polymer layers includes a plurality of first polymer layers, each of which has a first refractive index, and a plurality of second polymer layers, each of which has a second refractive index greater than the first refractive index. A difference between the first refractive index and the second refractive index is in a range of about 0.1 to about 0.6.

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 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.
