The present disclosure relates to a projector including a light source apparatus that outputs a light ray flux containing fluorescence, a bandpass filter provided at least in part of an optical path of the fluorescence, an integrator unit on which the light ray flux is incident and which divides the light ray flux into a plurality of partial light ray fluxes, a superimposing lens that is provided on the downstream of the integrator unit and causes the plurality of partial light ray fluxes to be incident in different positions, a light modulator including a plurality of pixels, a microlens array including a plurality of microlenses corresponding to the plurality of pixels, and a projection optical apparatus that projects light outputted from the light modulator.
