Abstract:
An object of the present invention is to provide a transmission decorative film having transparency and capable of applying different visual effects on observation surfaces. The transmission decorative film includes: a linear polarization plate; a first λ/4 plate laminated on one main surface of the linear polarization plate; a first cholesteric liquid crystalline layer laminated on the first λ/4 plate; a second λ/4 plate laminated on the other main surface of the linear polarization plate; and a second cholesteric liquid crystalline layer laminated on the second λ/4 plate, in which the first cholesteric liquid crystalline layer and the second cholesteric liquid crystalline layer respectively have wavelength selective reflectivity and reflect light which is right circularly polarized light or left circularly polarized light at a selective reflection wavelength.
