Abstract: 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.

Abstract: This invention provides a stereoscopic image display method and apparatus. The method includes the steps of dividing each of a plurality of parallax images supplied from a parallax image source having parallax image information into stripe pixels, displaying, on a display, a single stripe image by arranging and synthesizing some of the stripe pixels in a predetermined order, displaying a slit pattern consisting of a light-transmission portion and a light-shielding portion arranged at a predetermined pitch on a spatial light modulation element arranged at a predetermined position on the front or rear side of the display, inputting light transmitted through the stripe pixels, corresponding to the right and left eyes of an observer, of the stripe image to the right and left eyes of the observer via the spatial light modulation element and synchronously displaying the stripe pattern and the slit pattern in units of pixels or scan lines on corresponding scan lines of the display and the spatial light modulation element.

Abstract: A stereoscopic image display apparatus for stereoscopically viewing an image displayed on a display (1), by transmitting light through a mask pattern (7) where plural apertures (6a,6b) and plural light shielding portions (6c) are arranged in a predetermined pitch in the horizontal and vertical directions, transmitting the luminous flux through an optical system for illuminating the display (1) where at least two parallax images are displayed, and leading the luminous flux based on the two parallax images displayed on the display to the right eye and left eye of a viewer respectively. The apparatus enables to give flexibility to precise adjustment during the assembly and enables the viewing of a stereoscopic image from a wide area with good quality, by setting vertical widths Vt and Vs of the aperture (6a,6b) and the light shielding portion (6c) of the mask pattern (7), and horizontal widths Ht and Hs of the aperture (6a,6b) and the light shielding portion (6c) of the mask pattern (7) to satisfy the relationship of Vt

Abstract: A small optical system that is capable of widening an angle of view is provided. This optical system is provided with a first surface having a reflecting action and a second surface that reflects a light beam reflected on this first surface toward the first surface again. Then, a principal ray at central angle of view that is made incident on the first surface again is reflected and travels to a side opposite to a side of the last time it was reflected from the first surface with respect to a normal line of a surface at a hit point thereof.
