ABSTRACT:
An image display apparatus, e.g., a head-mounted display apparatus, which uses a half-mirror or a beam splitter prism and yet has an even more compact structure and provides a favorably flat image surface. A half-mirror (S) is obliquely disposed in front of an observer's eyeball (1), and an image display device (3), e.g., a liquid crystal display device, and a magnifying reflecting mirror (4) are disposed to face each other across the half-mirror (S) and to extend parallel to the observer's line of sight. To widen the field angle without increasing the size and weight of the optical system considerably, at least one surface (L) having positive refractive power is interposed between the eyeball (1) and the half-mirror (S). An even more compact arrangement is obtained by using a beam splitter prism in place of the half-mirror (S).
