Original Abstract Submitted
A display apparatus is provided, which may improve light extraction efficiency of light emitted from a light emitting element layer. The display apparatus comprises a substrate having a plurality of 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 on the pattern portion, wherein the plurality of subpixels include an overcoat layer having a first layer on the substrate and a light extraction portion adjacent to the reflective portion, having a plurality of concave portions formed on the first layer, an optimal radius Rof the concave portion satisfies R=0.15 sin 4π(AR+0.05)+1.5n+0.5m−0.59, wherein ‘π’ is a circumferential rate, AR is an aspect ratio of the concave portion, ‘n’ is a refractive index of the first layer, and ‘m’ is a variable value according to a process of forming the plurality of concave portions.
