(Thickness: 100 占 퐉), an adhesive film (thickness: 50 占 퐉), a second PET (polyethylene terephthalate) film having a glass transition temperature of -35 占 폚 or less and a (meth) acrylic copolymer having hydroxyl groups and organic nanoparticles, (100 cm x 160 cm) of a five-layered structure (100 cm x 160 cm) of a film (thickness: 50 μm), an adhesive film (thickness: 50 μm) and a third PET film The measuring device was fixed so as to be folded in the direction of the third PET film so that a half of the longitudinal length of the specimen was folded, and folded at 180 degrees so that the radius of curvature became 3 mm. Ii) bending (folding) (one cycle of folding and bending the specimen in half) at one or more of the following conditions: i) at -20 DEG C, ii) at 60 DEG C and 93% relative humidity, Adhesion with a folding number of 50,000 times or more until peeling, cracking, or bubble formation occurs Film, an optical member including the same, and an optical display device including the same are provided. |
