We have developed a 100-inch slim liquid-crystal rear projection display. Cross-dichromatic mirrors are used to combine three colors. Projection lenses were designed to decrease the color shading induced by these mirrors. In order to make the set slim, the projection lenses were also designed to have a short projection distance. To obtain good contrast ratio characteristics, the central axis of the projection lenses is inclined to that of the LCD panels. Transversal magnification color aberrations, which induce convergence error of the three colors on the screen are few. By using these technologies, we have developed a slim set with a depth of 1.1 m.
