To provide an augmented reality display device with an enhanced sense of realism of display images.SOLUTION: An augmented reality display device causes a user to visually recognize first and second images at different distances in a state where a real environment can be visually recognized. The augmented reality display device includes: a display panel that emits polarized lights for the first and second images; a surface-divided polarization conversion member arranged at a position where the polarized lights enter; and an optical element and a concave half mirror arranged at a position where the polarized lights transmitted through the surface-divided polarization conversion member enter. The surface-divided polarization conversion member has, in a plan view, a first transmissive portion that transmits the polarized light for the first image and a second transmissive portion that transmits the polarized light for the second image and causes a phase difference different by λ/2 from that caused by the first transmissive portion. The optical element makes a virtual image distance of the first image generated from the first polarized light transmitted through the first transmissive portion different from a virtual image distance of the second image generated from the second polarized light transmitted through the second transmissive portion.SELECTED DRAWING: Figure 7
【課題】表示画像の臨場感が向上した現実拡張型表示装置を提供する。【解決手段】現実の環境を視認可能な状態で、距離の異なる第一及び第二の画像をユーザーに視認させる現実拡張型表示装置であって、第一及び第二の画像用の偏光を出射する表示パネルと、前記偏光が入射する位置に配置された面分割偏光変換部材と、前記面分割偏光変換部材を透過した前記偏光が入射する位置に配置された光学素子及び凹面ハーフミラーと、を備え、前記面分割偏光変換部材は、平面視において、第一の画像用の偏光を透過させる第一の透過部と、第二の画像用の偏光を透過させ、かつ前記第一の透過部よりもλ/2異なる位相差を生じさせる第二の透過部と、を有し、前記光学素子は、前記第一の透過部を透過した第一の偏光から生成する第一の画像の虚像距離と、前記第二の透過部を透過した第二の偏光から生成する第二の画像の虚像距離とを異ならせる、現実拡張型表示装置。【選択図】図7
