N2 - The optical design of projection objectives is a key to the LCD projection technology, which will have a great impact on the quality of projection image. The method of the design for the LCD projection objective is very close to that for photographic lens. In this paper, a LCD projection objective is designed. Based on the inverse telephoto objective, the initial optical structure is obtained through complication so that the seven primary aberrations of the initial system can be corrected. The optical design software ZEMAX is employed to have the initial system optimized. The optimization result meets the technique requirements: the effective focal length 50mm, F/6, the full field of view ±20°, distortion greater than 0.1% and MTF above 0.1 at 40lp/mm.
