摘要： A light-source device comprising: a rod integrator having an injection end and an emitting end; a lens unit for collecting a luminous flux emitted from the emitting end; and, a diaphragm. The rod integrator forms a plurality of imaginary light-source points, each of which virtually emits the luminous flux toward the emitting end. The diaphragm is disposed in the vicinity of a plane on which the lens unit forms the images of the imaginary light-source points, and selectively blocks luminous flux emitted from each of the images of the imaginary light-source points.

摘要： A reflection surface (1a) of a mirror (1) has a rotationally-symmetrical shape about an optical axis (110). The mirror (1) is rotatably supported by a pivot supporting portion (41) on the position of the optical axis (110) of the reflection surface (1a) or in the vicinity of the optical axis (110). Furthermore, the mirror (1) is slidably supported by slide supporting portions (42) at two positions on the upper part thereof. With such a configuration, the mirror (1) is supported at three points. Further, even when the mirror (1) expands and contracts due to the change in temperature or the like, the deformation of the reflection surface (1a) of the mirror (1) is prevented by the action of the slide supporting portions (42). As a result, it is possible to prevent the generation of distortion of an image projected on a screen (300).
