摘要:
A compact wide-view angle image display apparatus which displays an image by using an optical system. A lens unit (L1) is disposed on the optical axis (A1) of an LCD (11). A magnifying reflecting mirror (12) is disposed on an optical axis (A2) perpendicularly intersecting the optical axis (A1). A half-mirror surface (13) is disposed at a tilt on the intersection point of the optical axis (A1) and the optical axis (A2) so that the half-mirror surface (13) reflects a bundle of rays from the LCD (11) to the reflecting mirror (12) and transmits the ray bundle reflected from the reflecting mirror (12). A magnifying reflecting mirror (14) is disposed to face the reflecting mirror (12). A half-mirror surface (15) is disposed at a tilt on the intersection point of the optical axis (A2) and an observer's visual axis (AE) so that the half-mirror surface (15) transmits the ray bundle reflected from the reflecting mirror (12) to the reflecting mirror (14) and reflects the ray bundle reflected from the reflecting mirror (14) to project it into an observer's eyeball. A lens unit (L2) of positive power is disposed between the half-mirror surface (15) and the eyeball.
