Abstract:
In an optical unit, illumination light is directed to a plurality of digital micromirror devices that produce projection light by modulating the illumination light on an image display surface according to an image signal. The optical unit emits the projection light produced by the digital micromirror devices. The optical unit includes: a reflector having an illumination light reflecting face on which the illumination light is reflected; and a prism unit composed of a plurality of first prisms. The reflected illumination light enters the prism unit via a first face of a most emergence-side first prism among the first prisms and the projection light exits via the first face.

Claim (Index 1):
An optical unit in which illumination light is directed to a plurality of digital micromirror devices that produce projection light by modulating the illumination light on an image display surface according to an image signal, wherein the optical unit emits the projection light produced by the digital micromirror devices, the optical unit comprising:\n a reflector having an illumination light reflecting face on which the illumination light is reflected; and a prism unit composed of a plurality of first prisms, wherein the reflected illumination light enters the prism unit via a first face of a most emergence-side first prism among the first prisms and the projection light exits via the first face, wherein the reflector is disposed next to the first face and protrudes from the first face in a projection light exiting direction, an optical axis of the illumination light striking, as incident light, the illumination light reflecting face and an optical axis of the projection light on the first face are on a same plane, wherein the same plane is an optical axis plane, when a first outward normal vector to the first face is projected onto the optical axis plane, a first component vector is obtained by the first outward normal vector being projected on a same side as the optical axis of the incident light with respect to the optical axis of the projection light, and the first component vector points in a direction along which the farther away the first component vector is from the first face, the farther away the first component vector is from the optical axis of the projection light leaving the first face.
