Abstract
A three-dimensional display device includes: a first image display that outputs linearly polarized first image light; a second image display that outputs linearly polarized second image light; a first retardation plate that modulates and converts the first image light output from the first image display to first elliptically polarized light; a second retardation plate that modulates and converts the second image light output from the second image display to second elliptically polarized light that rotates in a direction identical to a rotation direction of the first elliptically polarized light; and a half mirror that transmits the first elliptically polarized light, converts the first elliptically polarized light to first circularly polarized light that rotates in a direction identical to the rotation direction of the first elliptically polarized light, reflects the second elliptically polarized light, and coverts the second elliptically polarized light to second circularly polarized light that rotates in a direction opposite the rotation direction of the second elliptically polarized light.
