Abstract
The display device of the present invention includes, in the following order toward a viewer: a display panel; a semi-transparent mirror; a Pancharatnam-Berry lens configured to cause one-handed circularly polarized light incident thereon that is left-handed circularly polarized light or right-handed circularly polarized light to converge while causing opposite-handed circularly polarized light incident thereon to diverge; and a circularly polarized light-selective reflector.
Claims10
A display device comprising, in the following order toward a viewer:
- a display panel;
- a semi-transparent mirror;
- a lens;
- a Pancharatnam-Berry lens configured to cause one-handed circularly polarized light incident thereon, that is left-handed circularly polarized light or right-handed circularly polarized light, to converge, while causing opposite-handed circularly polarized light incident thereon to diverge;
- and
- a circularly polarized light-selective reflector.
A display device comprising, in the following order toward a viewer:
- a display panel;
- a semi-transparent mirror;
- a first Pancharatnam-Berry lens configured to cause one-handed circularly polarized light incident thereon, that is left-handed circularly polarized light or right-handed circularly polarized light, to converge, while causing opposite-handed circularly polarized light incident thereon to diverge;
- a circularly polarized light-selective reflector;
- and
- a second Pancharatnam-Berry lens disposed between the semi-transparent mirror and the circularly polarized light-selective reflector, and configured to cause one-handed circularly polarized light incident thereon, that is left-handed circularly polarized light or right-handed circularly polarized light, to converge, while causing opposite-handed circularly polarized light incident thereon to diverge.
