To reduce reflection on a surface of a projection target member to prevent the occurrence of double images.SOLUTION: An image creation unit 21 emits display light. A relay optics directs the display light from the image creation unit 21 to a projection target member. A polarized light patterning optical member 50 is arranged on a light path of the display light from the image creation unit 21, and so as to bring the direction of the polarization axis E of the display light reflected in each of the areas of the projection target member closer to incident light of a P-polarized light in each of the areas of the projection target member, continuously or gradually makes the polarization axis E of the display light different in accordance with an incident area of the display light.SELECTED DRAWING: Figure 8

    【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】画像生成部21は、表示光を出射し、リレー光学は、画像生成部21からの表示光を被投影部材に向け、偏光パターニング光学部材50は、画像生成部21からの表示光の光路上に配置され、被投影部材の各領域それぞれで反射される表示光の偏光軸Eの方位が、被投影部材の各領域におけるP偏光の入射光に近づくように、表示光の入射領域に応じて、表示光の偏光軸Eを連続的又は段階的に異ならせる。【選択図】 図8
