Abstract
Provided are projectors, each including a light source configured to emit laser light, a substrate spaced apart from the light source by a distance, a pattern mask including a pattern on a first surface of the substrate, the first surface facing the light source, and a meta-lens including a plurality of first nanostructures on a second surface of the substrate, the second surface facing the first surface, the nanostructures having a shape dimension of a sub-wavelength that is less than a wavelength of light emitted from the light source.
