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.
