To reduce reflection on a surface of a projection target member to prevent the occurrence of double images.SOLUTION: A head-up display device projects display light on a projection target member 60 to allow an observer who arranges the eyes in an eye box to visually recognize a virtual image. A polarized light control element 50 is arranged on a light path of the display light from a display 21, and adjusts the direction of the polarization axis E of the display light for each of the areas on which the display light is incident. A processor executes polarized light pattern control of making the direction of the polarization axis E for each of the areas of the polarized light control element 50 different so as to reduce reflection on a surface of the projection target member 60 based on the positions of the eyes of the observer.SELECTED DRAWING: Figure 10

    【課題】被投影部材での表面反射を低減し、2重像の発生を抑制する。【解決手段】被投影部材60に表示光を投影することで、アイボックスに目を配置する観察者に虚像を視認させ、偏光制御素子50は、表示器21からの表示光の光路上に配置され、表示光を入射する領域毎に、表示光の偏光軸Eの方位を調整し、プロセッサは、観察者の目位置に基づき、被投影部材60による表面反射が低減されるように、偏光制御素子50の領域毎に、偏光軸Eの方位を異ならせる偏光パターン制御を実行する。【選択図】 図10
