摘要:
An image display apparatus designed so that the observer can view the image of an image display device without the need of manually adjusting the positional relationship between the observer's eyeball and a bundle of rays from the image display device which is to be projected into the eyeball. A positional relationship detecting section (46) observes the pupil of an observer's eyeball (44) and its vicinities, and detects where a bundle of rays from an LCD (42) is being projected. If it is detected that the ray bundle is not coincident with the pupil, motors (52a and 52b) are driven to move a first support (50a) and a second support (50b), which support the LCD (42), a backlight (43), and an ocular lens (45), so that the ray bundle passes through the pupil.
