Abstract
An image display system wearable on the user's head is disclosed for displaying a magnified projected image. The image display system includes an image display element for displaying an image thereon, a right eye ocular optical system for forming a light path leading an image formed on the image display element onto the right eye of the viewer, a left eye ocular optical system for forming a light path leading an image formed on the image display element onto the left eye of the viewer, thereby viewing a spatially enlarged projection of the image by both the right and left eye ocular optical systems. The right eye ocular optical system for leading the image from the LCD 1 to the right eye 5R includes a half-mirror 3R and a convex lens 4R. The left eye ocular optical system for leading the image to the left eye 5L includes a half-mirror 3L and a convex lens. The LCD 1 is placed at a position at substantially equal distance from the right and left eyes. In order to illuminate the LCD 1, the right eye illuminating system 2R is placed at the side of the left ocular optical system, and the left eye illuminating system 2L is placed at the side of the right eye ocular optical system. The LCD 1 is illuminated by the pencil of rays from the right and left eye illuminating means, alternately, thereby leading the image time-divisionally to the right and left eyes 5L,5R of the viewer.
