ABSTRACT:
A space light modulating apparatus includes a modulating unit that modulates incident light based on an image signal including a plurality of pixels and a light-shielding part placed between the pixels, and a refracting unit that refracts modulated light including a group of prisms formed with a prism element that has at least a refracting surface. Light from the pixels is incident on at least a part of the prisms. A direction of the refracting surface is such that a projection image of the pixels is guided onto a projection image of the light-shielding part on a projection surface at a predetermined distance. The refracting surface and a reference surface formed in a direction perpendicular to an optical axis make a predetermined angle.
