Japanese Patent JP6021200

B2

The projector comprises: at least one light source; a light separation unit separating light emitted from the light source into a first and second lights in different wavelength bands; a TIR prism through which the first and second lights pass; an optical modulating element irradiated with and modulating the first and second lights to emit the modulated first and second lights toward the TIR prism; a projection lens expanding and projecting the light which is modulated by the optical modulating element and passes the TIR prism; a rotating prism which is rotatably arranged in the light path between the light separation unit and the TIR prism and emits, from different positions in accordance with rotation, the first and second lights emitted from the light separation unit; and a control unit which, when the image signals representing a first and second images are supplied, causes the optical modulating element to perform modulation according to the image signal of the first image with regard to the area irradiated by the first light and to perform modulation according to the image signal of the second image with regard to the area irradiated by the second light.
