Abstract
A display device includes a substrate, a partition wall on the substrate, a light-emitting element in an emission area partitioned by the partition wall on the substrate, and extending in a thickness direction of the substrate, a wavelength conversion layer over the light-emitting element in the emission area, and including a base resin, and a scatterer dispersed in the base resin and that converts a wavelength of light emitted from the light-emitting element, a light-blocking member on the partition wall, and at least one optical pattern on the wavelength conversion layer in the emission area, and having an upwardly protruding shape.
