Projector having integrator with greater illuminance in offset direction of projection lens and modulator

A projector comprising:

• a light source unit that outputs light;
• a lens integrator system;
• a light modulator having an image formation region where light from the lens integrator system is modulated in accordance with image information;
• and
• a projection system that projects light from the light modulator,
• wherein the projection system is so disposed that the optical axis of the light incident on the projection system is shifted from the optical axis of the projection system in a predetermined direction when the projection system is viewed in the direction in which the light travels toward the projection system, and
• the lens integrator system is so configured that illuminance of the light on a first side corresponding to the predetermined direction in the image formation region is higher than illuminance of the light on a second side that is opposite the side corresponding to the predetermined direction in the image formation region.
