Abstract: A transparent projection screen and a manufacturing method. The transparent projection screen is for receiving projection light and transmitting ambient light and comprises a first substrate layer, a Fresnel structure layer, a surface diffusion layer, a nano metal plating layer, and a binding adhesive layer. The Fresnel structure layer is disposed on the first substrate layer and comprises a prism surface. The surface diffusion layer is disposed on a portion of the prism surface. The nano metal plating layer is disposed on the surface diffusion layer. The binding adhesive layer is disposed on the nano metal plating layer and fills and levels the prism surface. The projection light passes the first substrate layer and is incident on the prism surface and then reflected thereby. The ambient light passes the binding adhesive layer, the nano metal plating layer, the surface diffusion layer and the first substrate layer, and is emitted.
