An image projection device (100) of the present invention includes a display unit (300) to emit a display light representing a display image in a form of either of s-polarized light and p-polarized light and an optical laminate (200) that the display light emitted from the display unit (300) is incident on. The optical laminate (200) includes at least two substrates (210, 250) and an optical layer (230) to change a polarization direction of incident light by 90°. The display unit (300) has a polarization direction converter capable of freely switching between s-polarized light and p-polarized light.
