| titleOfInvention | Projection optical system |
| abstract | A projection optical system comprising a plurality of lenses and projecting an image from a liquid crystal display device is disclosed.n n n The disclosed projection optical system includes a front lens group in which a meniscus lens, a first concave lens, a convex lens, and a second concave lens are sequentially combined from a far side from the display element; And a curvature radius of the surface facing the image surface is infinite and the surface opposite to the image surface is composed of two flat convex lenses formed convexly. This projection optical system can provide an image of the liquid crystal display device with a small volume while adjusting the distance between the front lens group and the rear lens group. |
