Abstract

An organic light emitting display apparatus is disclosed, including a substrate having a plurality of subpixels; a pixel defining layer on the substrate and defining a light emitting opening; a partition wall on the pixel defining layer and defining a partition wall opening corresponding to the light emitting opening; and a light emitting element corresponding to the partition wall opening. The partition wall opening includes a center opening, a first partition wall opening extending in a first direction from the center opening, a second partition wall opening extending in a second direction overlapping the first direction, and a third partition wall opening extending in a third direction overlapping both the first and second directions. The plurality of subpixels is respectively disposed in the first, second, and third partition wall openings, enabling separation and arrangement of subpixels within a shared structure for efficient light emission without using a fine metal mask.
