Original Abstract Submitted
An augmented reality display device causes a user to perceive first and second images at different distances in a state where the user can perceive a real environment. The augmented reality display device includes: a display panel which emits polarized lights for first and second images; a surface-divided polarization conversion component; and an optical element and a concave semi-transparent mirror. The surface-divided polarization conversion component in a plan view includes: a first transmissive part; and a second transmissive part which introduces a phase difference different by λ/2 from a phase difference introduced by the first transmissive part. The optical element makes a first image generated from the first polarized light transmitted through the first transmissive part different in virtual image distance from a second image generated from the second polarized light transmitted through the second transmissive part.
