A decorative film is provided. The decorative film comprises: a plastic substrate, comprising a surface, and a plurality of optical film layers, being formed by laminating optical film layers of at least two different materials onto the surface, wherein each of the optical film layers and another optical film layer are stretched in at least one direction to create a difference in refractive indices of no less than 0.1 between the optical film layers. |
