ABSTRACT:
A head-mounted visual display apparatus which uses two or more two-dimensional display devices and which is compact, lightweight and enables an image which is clear as far as the periphery of the observation image field to be observed at a wide field angle and high resolution. The apparatus has a first two-dimensional display device (4) and a second two-dimensional display device (5). An ocular optical system (3) includes a first surface (11) having both reflecting and transmitting actions, a second surface (12) having at least reflecting action, and a third surface (13) having at least reflecting action. The first surface (11) is disposed to face an observer's eyeball (6). The second surface (12) is disposed to face the first surface (11). The third surface (13) is disposed to face the first surface (11) in a side-by-side relation to the second surface (12). Thus, images displayed by the first and second two-dimensional display devices (4 and 5) are led to the observer's eyeball (6).
