    摘要： There is provided a projection image display apparatus which is excellent in quality of a display screen image even if a projection lens using a plastic lens having an asymmetrical shape with respect to an optical axis is used. The apparatus includes a projection lens which obliquely projects video light on a screen, an integrator which aligns a polarization direction of light from a light source, and an image display element (P, PL) which modulates light having the aligned polarization direction by an image signal. The projection lens includes multiple plastic lenses, and each of the multiple plastic lenses is arrayed, respectively, by shifting a gate direction to each other by 180 degrees. When the projection lens includes n sheets (n is a natural number) of plastic lenses, each of the multiple plastic lenses may be arrayed, respectively, by shifting a gate direction to each other by (360/n) degrees.
