Claim 7:
8. A light-emitting apparatus comprising:
a light-emitting layer for emitting light; and
at least one metasurface layer in front of the light-emitting layer for directing the light emitted from the light-emitting layer in a first polarization state towards a first FOV and directing the light emitted from the light-emitting layer in a second polarization state towards a second FOV;
wherein the first and second FOVs are overlapped and laterally offset from each other for forming a three-dimensional (3D) perception to a user wearing a pair of glasses with lenses of different polarization states.
