<p>PROBLEM TO BE SOLVED: To provide a transmission type screen that suppress the influence of external light to allow an observer to observe transmitted videos with high contrast and observe the state on the rear surface side of the screen, which is on the opposite side of the observer side across the screen, even when video light is projected from a video source, which is arranged on the opposite side of the observer side across the screen at a large incident angle on the screen; and a video display system including the transmission type screen.SOLUTION: A transmission type screen has a plurality of unit lens parts each having a lens surface inclined relative to the screen, and background transmission parts each provided between the unit lens parts. The lens surface of the unit lens part has a reflection layer formed thereon, and the background transmission part is in a state where a flat surface parallel to the screen is exposed.</p> |
