Abstract: Provided is an organic light emitting display device. An organic light emitting display device includes an organic light emitting element and a light scattering layer disposed on a bottom or a top of the organic light emitting element. The light scattering layer includes a photosensitive resin and dispersion particles dispersed in the photosensitive resin. The dispersion particles are configured to improve light extraction with respect to light emitted from the organic light emitting element and compensate a viewing angle with respect to the light emitted from the organic light emitting element.
