Abstract
A visual display apparatus, for example, a head-mounted display apparatus, which enables an image to be observed at a wide field angle and high resolution. The apparatus includes a pair of two-dimensional display devices (4 and 5) disposed with their display surfaces facing each other, and two half-mirrors (6 and 7) which are paired with the display devices (4 and 5) and combined to each other in the shape of a V. The apparatus further includes a concave mirror (8) having a center axis coincident with the center axis of the half-mirrors (6 and 7) combined in a V shape. The two-dimensional display devices (4 and 5) are adapted to display images (11 and 10) each including an overlap region (9) and having an area wider than one half of the image for observation. The images (11 and 10) are combined together into one continuous image by the two half-mirrors (6 and 7) combined in a V shape.
