A projector includes: a light source that emit light; an illumination optical system that includes a superimposing optical element capable of performing superimposition illumination and uniformizes the light emitted from the light source to form illumination light; a color separating optical system that includes a dichroic mirror which reflects a predetermined color light component of the illumination light and transmits other light components, thereby separating the light components into a first optical path and a second optical path, a first mirror which bends the first optical path, and a second mirror which bends the second optical path, and adjusts the reflection angle of the predetermined color light component by the dichroic mirror and the bent angles of the optical paths by the first and second mirrors to provide a predetermined difference between the length of the first optical path and the length of the second optical path, the predetermined difference corresponding to a difference between the focal, distances of the first and second optical paths; light modulating devices that are illuminated by the color light components emitted from the color separating optical system and form color optical images; a combining optical system that combines the color optical images; and a projection optical system that projects an image combined by the combining optical system.
