Display apparatus and display method

A display apparatus, comprising

• a group-of-viewpoints generation system that includes a plurality of three-dimensional image displaying apparatuses corresponding to each of two eyes of a user, the group-of-viewpoints generation system generating a group of viewpoints for the eye using a group of light rays emitted from each of the plurality of three-dimensional image displaying apparatuses,
• wherein the plurality of three-dimensional image displaying apparatuses includes at least one pair of first and second three-dimensional image displaying apparatuses in which a direction in which the group of light rays is emitted from the first three-dimensional image displaying apparatus and a direction in which the group of light rays is emitted from the second three-dimensional image displaying apparatus intersect, and
• wherein the group-of-viewpoints generation system includes an optical system that guides the group of light rays coming from each of the plurality of three-dimensional image displaying apparatuses,
• wherein the optical system includes a first optical element that aligns a traveling direction of a first group of light rays and a traveling direction of a second group of light rays, the first group of light rays being the group of light rays coming from the first three-dimensional image displaying apparatus, the second group of light rays being the group of light rays coming from the second three-dimensional image displaying apparatus,
• wherein the plurality of three-dimensional image displaying apparatuses further includes a third three-dimensional image displaying apparatus,
• wherein a traveling direction of a pair of groups of light rays and a traveling direction of a third group of light rays intersect, the pair of groups of light rays including the first and second groups of light rays coming from the first optical element, the third group of light displaying apparatus, and
• wherein the optical system further includes a second optical element that aligns the traveling direction of the pair of groups of light rays and the traveling direction of the third group of light rays.
