Claim:
1. A projection display apparatus comprising: a laser light source which emits a blue light; a wheel which includes a light emitting body provided on a reflection surface of a substrate, the light emitting body emitting an emission light when the emitting body is irradiated with the blue light; a bandpass filter which is disposed on an optical path on which the emission light of the light emitting body travels; a plurality of optical modulating elements which modulate the blue light and the emission light from the light emitting body; a projection unit which projects the light modulated by the plurality of optical modulating elements; and a combining optical element which combines the emission light and the blue light to emit a combined light, wherein the bandpass filter allows transmission of part of lights whose wavelength bands are 560 nm to 590 nm in the emission light of the light emitting body, and reflects other lights and is disposed on the optical path on which an emission light from the combining optical element travels.
