摘要： A light source apparatus is disclosed which is capable of emerging predetermined linearly polarized light while a loss of light amount is reduced. The light source apparatus comprises plural light-emitting elements which are disposed so that their light-emitting surfaces face the direction of an emergence surface of the light source apparatus, and a polarization selective element which transmits a light component with a first polarization direction and reflects a light component with a second polarization direction different from the first polarization direction. The apparatus further comprises a reflecting surface which is disposed at a position closer to the light-emitting elements than the polarization selective element and reflects the reflected light from the polarization selective element to the polarization-selective element side.

摘要： A display optical system for guiding light from an original picture to an eye of an observer or a surface to have an image projected thereon is provided with a first optical system and a second optical system. The first optical system is provided with a first surface that is formed on a transparent body and has at least a reflecting action, a second surface for reflecting light reflected on the first surface toward the first surface again, and a third surface that is formed on the transparent body in the same manner as the first surface and transmits the light from the original picture. The light transmitted through the third surface travels toward the first surface and reflected for the first time on the first surface. In addition, a principal ray at central angle of view to be reflected for the last time on the first surface is reflected and travels to a side opposite to a side of the first reflection on the first surface with respect to a normal line of a surface on a hit point thereof. With such a structure, a small display optical system that is capable of widening an angle of view is realized.

摘要： Parallax images corresponding to a plurality of different view points are each divided into predetermined stripe images, a synthetic parallax image is synthesized from the stripe images, and display light, from stripe images corresponding to one view point of the synthetic parallax image on the image display element displaying the synthetic parallax image, is guided to a mask member having a mask pattern with predetermined openings and shields by a second optical system placed in front of the image display element. The display light passing through the openings of the mask member is condensed to a position corresponding to the view point on an observation surface a predetermined distance apart, by a first optical system, whereby an observer is permitted to stereoscopically observe image information displayed on the image display element.
