To provide a projection device, a display system, and a movable body that prevent a reduction in image quality due to a difference in optical path length between an image forming unit and an image formation optical system.SOLUTION: A projection device 100, a display system 1, and a movable body 1A comprise an image forming unit 13 that emits image light for forming an image, and an image formation optical system 30 that reflects the image light to be formed into an image. The image formation optical system 30 is configured such that the magnification at a position on which image light having a short optical path length between the image forming unit 13 and the image formation optical system 30 is incident becomes higher than the magnification at a position on which image light having a long optical path length between the image forming unit 13 and the image formation optical system 30 is incident.SELECTED DRAWING: Figure 20
【課題】画像形成部と結像光学系の間の光路長が異なることに起因する画像品質の低下を抑制する投射装置、表示システムおよび移動体を提供すること。【解決手段】投射装置100、表示システム1および移動体1Aは、画像を形成する画像光を出射する画像形成部13と、画像光を反射して像を結像させる結像光学系30と、を備え、結像光学系30は、画像形成部13と結像光学系30の間の光路長が短い画像光を入射する位置の倍率が、画像形成部13と結像光学系30の間の光路長が長い画像光を入射する位置の倍率よりも高くなるように構成される。【選択図】図20
