PROBLEM TO BE SOLVED: To provide a projection screen used even under bright environment, having high lightness and capable of preventing electrification. SOLUTION: The projection screen has a base plate and a polarized light selective reflection layer formed on the base plate and having a selective reflection function to selectively reflect the light of a specified polarized light component and a diffuse reflection function to diffuse and reflect the light of the specified polarized light component, and reflects video light radiated from a projector so as to display a video. Then, an electrification preventing layer for preventing the electrification of the projection screen is provided at least on either the front surface side or the back surface side of the projection screen.
