To provide a projector capable of increasing F number of an illumination system without enlarging the size of the illumination system or the like. A combining lens 43a operating in cooperation with a superimposing lens 35 is provided only in a first section between a first dichroic mirror 41a and a red light reflection mirror 42a as a bending mirror on a first optical path OP1 extending from the superimposing lens 35 to a first liquid crystal display panel 61r. Thus, the F number of an illumination system 30 associated with blue light can be controlled with high degree of freedom, and the number of lenses constituting a color separation and light guide system 40 and the illumination system 30 does not increase. Moreover, the incident angle of illumination light does not become large around the first liquid crystal display panel 61r, and thus the telecentric characteristics of the illumination system 30 associated with blue light can be secured.
