Abstract
A holographic head-up display device has a light source portion that emits coherent light; an optical modulation portion that modulates the coherent light; a relay optical system that focuses the modulated light; a filter minor that has a reflection area at a focal position of the relay optical system and reflecting light incident through the relay optical system and an absorption area at the periphery of the reflection area and absorbing light incident through the relay optical system; and a transflective mirror that partially transmits and partially reflects light reflected by the filter minor.
