The projector includes a space light modulating apparatus that modulates incident light based on an image signal, and that outputs modulated light, and a group of prisms installed on output-side of the space light modulating apparatus. The space light modulating apparatus includes opening sections that are a plurality of pixels arranged in a matrix form and a black matrix placed between the opening sections. The group of prisms includes prism elements each of which has at least a refracting surface. Light from one of the opening sections is incident on at least one portion of the group of prisms. A direction of the refracting surface and a tilt angle are arranged so that an opening section image is guided onto a black matrix image on a screen a distance from the group of prisms.
