A total reflecting prism portion is formed on an image generation source
side of a Fresnel lens sheet which constitutes a rear projection type
screen. The total reflecting prism portion is formed in an area in which
the angle of incidence of a projection image projected from an optical
part on the Fresnel lens sheet is at least about 40. The total reflecting
prism portion causes incident light to be outputted as output light at a
predetermined output angle by a total reflection phenomenon after a first
refraction phenomenon. A refracting prism portion is formed on an image
monitoring side of the Fresnel lens sheet. The refracting prism portion
is formed in an area opposed to the portion where the total reflecting
prism portion is not formed. The refracting prism portion causes incident
light to be outputted as output light at a predetermined output angle by
a second refraction phenomenon.
