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
