Abstract
An augmented reality device includes an image output unit disposed at a preset angle from a horizontal direction to output an augmented reality image of a preset polarization direction, a polarization reflection film reflecting light of the preset polarization direction and transmitting other light than the light of the preset polarization direction, and an optical component disposed on a light path of an image output from the image output unit. The optical component has a preset refractive index and a preset shape. The polarization reflection film is applied on a first surface of the optical component which is positioned farther away from the image output unit.
