The present invention provides a Fresnel lens sheet capable of effectively preventing such troubles as the production of double images that occurs due to stray light. A Fresnel lens sheet (1) comprises a base (1a) in sheet form, and a plurality of prisms (2) formed on the incident side of the base (1a). Each prism (2) has a plane of refraction (3) that refracts imaging light (LS) projected from a projector (5), and a plane of total reflection (4) that totally reflects, toward the viewer's side, at least a part of the light that has been refracted at this plane of refraction (3). At least some of a plurality of the prisms (2) are so made that the imaging light (LS) that has passed through these prisms (2) emerges in the direction inclined toward the projector (5) side at predetermined angles (.gamma.b, .gamma.c) with respect to the normal perpendicular to the sheet plane of the base (1a).
