The “inclination” is effective when the upper part of the secondary image is located farther from the viewer E than the lower part thereof, and when its angle &thgr; is within a range of 3° to 40°. Further, a screen display apparatus, a plurality of secondary images (in the figures, virtual images and ) on a primary image as a subject are formed by a microlens array including convex microlenses and concave microlenses The screen display apparatus visually presents those secondary images to a viewer E so that those images are viewed as a single image. As a result, an image is displayed with an intensive three-dimensionally feeling.
