Abstract

A transmission decorative film includes a circular polarization plate and a circular polarization reflection layer disposed on the circular polarization plate. The circular polarization reflection layer includes at least one or more first cholesteric liquid crystalline layers that reflect any one of left circularly polarized light or right circularly polarized light. The first cholesteric liquid crystalline layer includes two or more reflection regions having different selective reflection wavelengths. The circular polarization plate transmits circularly polarized light having a revolution direction opposite to a revolution direction of the circularly polarized light reflected by the first cholesteric liquid crystalline layer.
