Abstract
An augmented reality (AR) device is provided. The AR device includes a display configured to output light of a first polarization; a polarization-conversion reflector provided opposite to an output side of the display, the polarization-conversion reflector converting the light of the first polarization into light of a second polarization that is orthogonal to the first polarization and reflect the light of the second polarization; a waveguide having a flat plate shape, a normal line of a flat surface of the flat plate shape being inclined with respect to an optical axis of the light of the first polarization output from the display, a side of the waveguide being provided between the display and the polarization-conversion reflector; an input-coupler inputting the light of the second polarization into the waveguide; and an output-coupler outputting light propagating in the waveguide.
