Abstract: Provided is a color filter. The color filter includes a nano structure layer including a base substrate and a plurality of nano structures which are disposed to be spaced apart from each other on the base substrate and each of which has an elliptical shape on a plane, and a polarization control layer disposed on the nano structure layer and including liquid crystal molecules of which an alignment direction on a plane parallel to the base substrate is controlled by an electric field to realize excellent color reproducibility.
