An image projection device (100) according to the present invention comprises: a display (300) projecting display light representing a display image in a state where the display light is converted into S polarized light or P polarized light; and an optical laminate (200) on which the display light projected from the display (300) is incident. The optical laminate (200) includes at least two substrates (210, 250) and an optical layer (230) shifting a polarization direction of the incident light by 90 degrees. The display (300) includes a polarization direction converting unit capable of freelyswitching between the S polarized light and the P polarized light.
本发明的影像投射装置(100)具备将呈示显示图像的显示光以S偏光或P偏光进行投射的显示器(300)、以及会入射从显示器(300)投射的显示光的光学层叠体(200)。光学层叠体(200)具有至少两个基材(210,250)、以及使入射的光的偏光方向转换90°的光学层(230)。显示器(300)具有能够将S偏光或P偏光任意地切换的偏光方向转换部。
