Abstract: A transparent screen includes a plurality of transparent plates arranged in a front-rear direction; and a screen main body, interposed between the transparent plates, configured to display video images projected from a front side or a rear side of the transparent screen to a user on the front side, and enable a rear background to be visually recognized by the user. In a cross section orthogonal to a part of an outer edge of the transparent screen, the transparent screen has a curved shape, and a length of a center line in a plate thickness direction of the transparent plate on an external side of the screen main body in a curvature radius direction of the curved shape is greater than a length of a center line of the transparent plate on an internal side of the screen main body.

Abstract: A transparent screen sheet that displays images projected from a front side of the transparent screen sheet and/or a rear side of the transparent screen sheet to a user on the front side, and causes the user on the front side to view a rear background behind the rear side. The transparent screen sheet includes an image display layer configured to display the images; and a resin film that holds the image display layer. A difference between a maximum value and a minimum value of retardations of the resin film measured by irradiating a main surface of the resin film with a light with a wavelength of 460 nm in a direction orthogonal to the main surface, within a region on the main surface that overlaps with the image display layer, is one fourth of the wavelength of the light or less.
