The overall arrangement of each cylindrical mirror forms a light and shadow effect, and the texture effect is formed due to the up-down bias and/or left-right bias, so that the decorative film has a better decorative effect.

Preferably, the texture structure is small short lines. The small short line includes a bottom surface in contact with the bearing layer and a top surface opposite to the bottom surface. The bottom surface includes two opposite sides, the two sides are not parallel to each other, and the top surface of the small short line is a non-horizontal surface.

Of course, the micro-nano structure layer may not have a residual adhesive layer. In some embodiments, the adhesive residue layer may serve as a carrier layer. The bearing layer can also be any one or combination of PET, PC, PMMA or PE. For example, if the carrier layer is a PET layer, apply light-curable adhesive on the PET layer, emboss and cure to form a micro-nano structure layer, and leave a residual adhesive layer; you can also directly form a micro-nano structure layer on the PET layer by printing or other means. The structural layer does not have a residual adhesive layer. The micro-nano structure layer is a colored structure layer, and/or, the bearing layer is a colored layer. The micro-nano structure layer can be colorless or colored, such as using colored heat-curable adhesive or light-curable adhesive.
