Abstract: A display apparatus is discussed, which can improve light extraction efficiency of light emitted from a light emitting element layer. In one example, the display apparatus includes a substrate having a plurality of pixels with a plurality of subpixels, a pattern portion disposed on the substrate and formed to be concave between the plurality of subpixels, a reflective portion on the pattern portion, and a plurality of lines for driving the plurality of subpixels. The plurality of subpixels include a light emission area and a non-light emission area adjacent to the light emission area, and the plurality of lines are disposed in the non-light emission area. Further, the pattern portion is provided to surround the light emission area, and at least one of the plurality of lines partially overlaps the pattern portion.

Abstract: A disclosed light emitting display apparatus includes a substrate; a pixel driving layer on the substrate and including a driving transistor; a cover layer covering the pixel driving layer; a plurality of light emitting elements, including a first light emitting element and a second light emitting element each having a first electrode on the cover layer and being adjacent to each other; a bank disposed on the cover layer and between the first electrode of the first light emitting element and the first electrode of the second light emitting element; and a capacitor overlapping with the bank. The capacitor may include a first metal layer connected with a first terminal of the driving transistor via the first electrode of one of the first and second light emitting elements, and a second metal layer connected with a gate of the driving transistor.
