Abstract:
1. A projector comprising: a solid-state light source; a diffuser member that diffuses light outputted from the solid-state light source and outputs the diffused light; an excitation light source; a phosphor that is excited by light outputted from the excitation light source and emits fluorescence; a light modulator that modulates the diffused light outputted from the diffuser member and the fluorescence emitted from the phosphor in accordance with image information; a projection system that projects the light modulated by the light modulator as a projected image; a first light blocking member that is disposed in an optical path between the diffuser member and the light modulator and has an opening formed around the optical axis of the diffused light; and a second light blocking member that is disposed in an optical path between the phosphor and the light modulator and has an opening formed around the optical axis of the fluorescence, wherein when an area of the opening of the first light blocking member viewed in the direction of the optical axis of the diffused light is defined as a first opening area A the ratio A
