Abstract: A display device may include: a substrate; a plurality of subpixels each of which includes an emitting area and a non-emitting area; an overcoat layer disposed over the substrate, and having a concave part located between the emitting areas; a first electrode layer disposed on a periphery of the concave part; a metal pattern layer disposed to cover a sloped portion of the concave part; and a bank layer covering the concave part, and disposed on the metal pattern layer. It is possible to improve light extraction efficiency.

Abstract: A display device is disclosed that is capable of enhancing light extraction efficiency and lower power driving through high luminance characteristics. The display device includes an insulation layer positioned on a substrate and including at least one concave portion including a flat portion and an inclined portion surrounding the flat portion in one subpixel. The display device further includes a bank layer positioned on the insulation layer and including an opening area in the subpixel where the opening area is surrounded by the inclined portion, and where a center point of an area of the concave portion does not overlap a center point of the opening area of the bank layer.

Abstract: A display apparatus is provided, which may improve light extraction efficiency of light emitted from a light emitting element layer. The display apparatus may include a substrate, pixels having a plurality of subpixels, a pattern portion disposed on the substrate and formed to be concave between the plurality of subpixels, and a reflective portion disposed to be inclined on the pattern portion. The plurality of subpixels may include a first layer and a second layer. The first layer may be adjacent to the reflective portion on the substrate and may include a plurality of concave portions. The second layer may be on the first layer. An inclination angle ? of the reflective portion may satisfy Taper ? Angle ? ( ? ) = 180 × log ? 0.11 × T L 2 + T H 2 ? , wherein TH is a maximum thickness of the second layer in the concave portion, TL is a thickness of the first layer on an extension line of TH, and ? is a circular constant.

Abstract: According to an aspect of the present disclosure, a display device includes a substrate including a plurality of sub pixels; a first electrode on the substrate and corresponding to each of the plurality of sub pixels; a bank on the first electrode and including an opening which exposes the first electrode; a partition on the first electrode in the opening; a light emitting layer on the first electrode and the partition; and a second electrode on the light emitting layer, in which the light emitting layer is disposed to have a structure disconnected by the partition in the opening.
