    • There is provided a projector having a point light source disposed to an edge of an optical fiber for transmitting exciting light and including a fluorescent illuminant for emitting fluorescence by being exited by the exiting light, a light collecting optical system for collecting the fluorescence emitted from the point light source, a reflective display device for reflecting the fluorescence collected by the light collecting optical system and overlapping the fluorescence with an image signal, an outgoing aperture for stopping down the fluorescence overlapped with the image signal by the reflective display device, wherein the outgoing aperture and the point light source are disposed side by side in the vicinity of the front focusing surface of the light collecting optical system. With this arrangement, a bright projected image can be obtained while disposing the outgoing aperture and the point light source sufficiently near to each other, reducing aberration, and reducing the diameter of a collecting lens so that the overall size of the projector can be reduced.
