Abstract
An image display apparatus that includes a first light collecting-reflecting device () which image light (L) from an image forming apparatus enters, and a second light collecting-reflecting device () which second light (L), of the image light, having passed through the first light collecting-reflecting device enters. The first light collecting-reflecting device has transmission action and light collecting-reflecting action with respect to the image light. The first light collecting-reflecting device collects and reflects first light (L), of the entering image light, toward a first conversion position in a viewer's eye (). The second light collecting-reflecting device has at least the light collecting-reflecting action with respect to the image light. The second light collecting-reflecting device causes the second light to reenter the first light collecting-reflecting device and collects and reflects the second light toward a second conversion position. The second conversion position is different from the first conversion position in a plane orthogonal to an optical axis of the viewer's eye.
