1. An image display device comprising:
a display device configured to display an image;
a liquid crystal element on which light emitted from the display device is incident, the liquid crystal element being configured to selectively allow one of P-polarized light or S-polarized light to exit the liquid crystal element;
a reflective polarizing member configured to reflect the one of the P-polarized light or the S-polarized light that has exited the liquid crystal element and to transmit the other of the P-polarized light or the S-polarized light; and
a reflecting member configured to reflect the other of the P-polarized light or the S-polarized light in the same direction as a travel direction of the one of the P-polarized light or the S-polarized light reflected by the reflective polarizing member, wherein:
the reflective polarizing member is configured to transmit the other of the P-polarized light or the S-polarized light reflected by the reflecting member.
