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： An image display apparatus has a light source, a reflective display device, an illumination optical system for guiding light from the light source to the display device to illuminate the display device, and a display optical system for guiding the light reflected by the display device to the pupil of an observer to allow the observer to observe an image displayed on the display panel. The illumination optical system and the display optical system have an optical element shared in part or are arranged so as not to interfere with each other, thereby providing the image display apparatus of compact structure. Particularly, where the display optical system is a thin optical system having a plurality of decentered, reflecting, curved surfaces, the appropriate illumination optical system is arranged, thereby providing the thin image display apparatus using the reflective display device.

摘要： The present invention relates to an image display apparatus suitable for a head mounted display which apparatus has been made compact as a whole by the use of a reflection type liquid crystal display element. The apparatus has a first optical element which has an incidence surface on which a light beam is incident, at least two curved reflecting surfaces made eccentric with respect to each other for reflecting the light beam incident from the incidence surface, and an emergence surface from which the light beam from the curved reflecting surfaces emerges. A reflection type image display device provided on the incidence surface side. A light beam from a light source is caused to enter from one of the two curved reflecting surfaces which comprises a half mirror surface, and emerge from the incidence surface and illuminate the image display device. The light beam from the image display device is caused to enter from the incidence surface of the first optical element and be reflected by the curved reflecting surfaces, and thereafter emerge from the emergence surface, and image information displayed by the image display device is observed from the emergence surface side.

摘要： The image display apparatus includes first and second display elements respectively displaying first and second original images, and an optical system presenting an enlarged combined image of the first and second original images with first and second light fluxes from the first and second display elements. The optical system includes at least one reflective surface. When a cross-section of the optical system on which optical paths of the first and second light fluxes are turned by reflections at the reflective surface is defined as a decentering cross-section, the first and second original images correspond to different view angles in the decentering cross-section. Light flux components respectively included in the first and second light fluxes and introduced to a same image point in the enlarged combined image are overlapped with each other on an exit pupil plane.
