Optical apparatus and near-eye display apparatus including the same

An optical apparatus comprising:

• a display panel configured to form an image;
• a polarizer configured to convert a light emitted from the display panel to have at least one of a first linear polarization and a second linear polarization;
• a polarization beam splitter configured to transmit a first light having the first linear polarization and reflect a second light having the second linear polarization;
• and
• an optical element group configured to transmit the first light transmitted through the polarization beam splitter in a different path from the second light,
• wherein the first light displays a first image having a first viewing angle, and the second light displays a second image having a second viewing angle that is greater than the first viewing angle.

A near-eye display apparatus comprising:

• a pupil tracker configured to track a pupil of a user;
• an optical apparatus configured to display a first image having a first viewing angle corresponding to a position of the pupil detected by the pupil tracker and a second image having a second viewing angle that is greater than the first viewing angle;
• and
• an optical element configured to direct the first image and the second image to eyes of the user,
• wherein the optical apparatus comprises:
• a display panel configured to form an image;
• a first polarization rotator configured to electrically control a light emitted from the display panel to have a first polarization state;
• a first ¼ wave plate configured to convert a polarization state of a light transmitted from the first polarization rotator from the first polarization state to a second polarization state;
• and
• an optical element group configured to display the first image having the first viewing angle and the second image having the second viewing angle based on the second polarization state of a light transmitted from the first ¼ wave plate.
