摘要
Provided are a projection lens unit that enables a reduction in the thickness of a projection system and a projection system employing the same. The projection lens unit includes a refractive optical unit including a plurality of lenses that enlarge and project an image produced by a display and a reflective optical unit including at least one reflecting mirror slanted with respect to the minor axis of the screen, the reflective optical unit reflecting the image passing through the refractive optical unit toward the screen. The projection lens unit does not interfere with a beam when the thickness of the projection system is decreased. Therefore, a projection system with a slim design as well as a large screen can be provided.
