To provide a video display system capable of making it difficult to visually recognize a reflected image in an interior of a video formed on a transparent screen.SOLUTION: A video display system comprises: a projection device that is arranged inside a vehicle, and projects an image; and a transparent screen that visibly displays the image projected from the projection device to an observer inside or outside the vehicle as a video, and it satisfies the following formula 1; (D+B)-(P+DOF/2)≥410 ... Formula 1. In formula 1, D is a distance [mm] between the projection device and the transparent screen, B is a distance [mm] between the transparent screen and an interior material of the vehicle, P is a distance [mm] where the projection device is just in focus, and DOF is a depth of focus [mm] of the projection device.SELECTED DRAWING: Figure 8

    【課題】透明スクリーンに結像された映像の内装における反射像を視認し難くできる映像表示システムを提供する。【解決手段】映像表示システムは、車両の内部に配置され、映像を投影する投影装置と、投影装置から投影された映像を車内側または車外側の観察者に映像として視認可能に表示する透明スクリーンとを備え、下記式1を満たす。(D+B)-(P+DOF/2)≧410 ・・・式1式1において、Dは投影装置と透明スクリーンとの間の距離[mm]、Bは透明スクリーンと車両の内装材との間の距離[mm]、Pは投影装置のピントがちょうど合う距離[mm]、DOFは投影装置の焦点深度[mm]を示す。【選択図】図8
