An illumination device includes: a light source which has an emission surface forming area where a plurality of emission surfaces are disposed; a plurality of converging lenses disposed in correspondence with the plural emission surfaces to converge emission lights emitted from the emission surfaces; a first fly-eye lens which divides lights converged by the plural converging lenses into a plurality of partial lights; a second fly-eye lens which converges the plural partial lights; and a condenser lens which stacks the plural partial lights converged by the second fly-eye lens on an illumination receiving area, wherein the plural converging lenses stack the emission lights on the first fly-eye lens.
