Abstract
An organic light emitting display device includes a substrate, a thin film transistor on the substrate, an organic light emitting element including a first electrode connected to the thin film transistor, an organic light emitting layer on the first electrode, and a second electrode on the organic light emitting layer, and a pixel definition film disposed on the substrate to expose a part of the first electrode. The pixel definition film includes nanoparticles that change a path of light emitted from the organic light emitting layer.
