1. A light-emitting apparatus comprising:
a polarization-control layer comprising a plurality of first pixels each for polarizing light emitted from a light-emitting layer and passing the polarized light therethrough; and
at least one optical-transformation layer each comprising a plurality of second pixels each corresponding to a respective first pixel and comprising a polarization-selective metasurface for selectively passing therethrough the polarized light from the corresponding first pixel that is polarized in a predefined polarization state.
