ABSTRACT:
A display apparatus having an image generator and a beam combiner including a hologram for displaying a reduced image by receiving beams from the image generator. A virtual image of an image generated by the image generator is formed in the vicinity of the beam combiner by virtue of the image reductioning function of the beam combiner, so that the displayed image is visible from a wider range of viewing positions.
