Abstract
Provided are meta-surface optical device and methods of manufacturing the same. The meta-surface optical device may include a meta-surface arranged on a region of a substrate and a light control member arranged around the meta-surface. The light control member may be arranged on or below the substrate. A material layer formed of the same material used to form the meta-surface may be disposed between the light control member and the substrate. Also, the meta-surface may be a first meta-surface arranged on an upper surface of the substrate, and a second meta-surface may be arranged on a bottom surface of the substrate. Also, the meta-surface may include a first meta-surface and at least one second meta-surface may formed on the first meta-surface, and the light control member may be arranged around the at least one second meta-surface.
