Projection lens system and projector

A projection lens system that projects projection light from a light modulator side to a screen side and which is telecentric on the light modulator side, the projection lens system comprising:

• a first meniscus lens that is disposed closest to the screen side, is convex on the screen side, and has negative refractive power;
• and
• a second meniscus lens that is disposed next closest to the screen side, is convex on the screen side, and has negative refractive power,
• wherein the first meniscus lens is made of plastic and at least one out of two curved surfaces thereof is aspherical, and
• a refractive power of the first meniscus lens is lower than a refractive power of the second meniscus lens,
• wherein the projection lens system has an arrangement of eleven lenses that include the first meniscus lens and the second meniscus lens and are respectively negative, negative, negative, positive, negative, positive, positive, negative, positive, positive, and positive in order from the screen side, with only the first meniscus lens being an aspherical lens.
