A new approach for optical system with waveguides is presented. Recently, Large Area Displays (LADs) tend to be located to airplane cockpits. According to this trend, Low Profile Head Up Displays (LPHUDs) are being developed, which can be installed to the cockpits avoiding interference with LADs by using holographic waveguides. However, the holographic waveguide has difficulties in realizing color display because of it’s own characteristics. We have succeeded in developing a new optical system for LPHUD, which has wide field of view, large head motion box, and excellent color performance, by using a prism waveguide.
