Abstract: A display device includes a bank including an opening exposing a surface of a base. The bank further includes side surfaces adjacent to an upper surface. The side surfaces slope downward from the upper surface toward an opening in an organic film pattern. A plurality of fine holes is formed on the upper surface and the side surfaces, the bank may also include a plurality of inner holes.

Abstract: A display device includes a light emitting element disposed on a substrate. A capping layer, an antireflection layer, and an encapsulation layer are sequentially disposed on the light emitting element. The capping layer includes a first capping layer disposed on the light emitting element, and a second capping layer disposed on the first capping layer and having a refractive index greater than a refractive index of the first capping layer. A thickness of the first capping layer is in a range of about 20 Å to about 400 Å, and a thickness of the second capping layer is in a range of about 60 Å to about 400 Å.

Abstract: A manufacturing method of a display device includes forming a light emitting element layer on a substrate, co-depositing bismuth (Bi) and ytterbium (Yb) on the light emitting element layer to form a first inorganic absorbing layer, and forming a reflection control layer on the first inorganic absorbing layer. In the co-depositing, a deposition temperature of bismuth (Bi) is in a range of about 500° C. to about 850° C., a deposition temperature of ytterbium (Yb) is in a range of about 300° C. to about 550° C., and an extinction coefficient of the first inorganic absorbing layer is less than or equal to about 3.
