1. A display device comprising:
a substrate;
a partition wall on the substrate;
a light-emitting element located in an emission area partitioned by the partition wall on the substrate and extended in a thickness direction of the substrate;
a wavelength conversion layer over the light-emitting element in the emission area, and comprising a base resin and wavelength conversion particles dispersed in the base resin and configured to convert a wavelength of light emitted from the light-emitting element; and
an optical member over the wavelength conversion layer and the partition wall and configured to adjust a path of light output from the wavelength conversion layer,
wherein the optical member comprises an optical layer and a first protruding pattern protruding from the optical layer toward the wavelength conversion layer.
