A transparent film is used with a projector which emits a projected light. The transparent film includes a transparent substrate; a light-scattering layer disposed at an upstream position of the transparent substrate with respect to the projected light, and including a plurality of microstructures configured to scatter the projected light; and a light-blocking layer disposed at an upstream position of the light-scattering layer with respect to the projected light, and including a plurality of separate light-blocking units, which are configured to partially block the projected light and partially allow the projected light to reach the light-scattering layer.
