1. A head-mounted display apparatus, comprising:
a display assembly, adapted to output light of an image;
a lens assembly, positioned in front of the display assembly and adapted to enlarge the image and produce a first aberration of a first direction; and
a planar optical assembly, positioned between the display assembly and the lens assembly,
wherein the planar optical assembly is adapted to produce a second aberration of a second direction opposite to the first direction to correct the first aberration,
wherein the display assembly comprises: a display component; and a first circular polarizer, adapted to convert light from the display component into circular polarized light,
wherein the planar optical assembly includes: polarization-dependent planar optics adapted to receive one or more of a right-handed or left-handed circular polarized light and convert at least a portion thereof into oppositely circular polarized light and leak any remaining light; and a polarization blocker, adapted to block the leaked light, and
wherein the polarization blocker is a second circular polarizer, and the second circular polarizer blocks the leaked light with original handedness and passes the opposite handedness light.
