Abstract
The composite film according to an embodiment adopts an acrylate-based binder and an acrylamide-based monomer in a single functional layer for antistatic, antifouling, and chemical resistant functions to exhibit flexible characteristics without deteriorating the adhesive strength to a substrate; thus, it can be applied as a cover window of a flexible display device.
Claims8
A cover window of a display device comprising a base film;
- and a functional layer formed on the base film, wherein the functional layer comprises an acrylate-based binder and an acrylamide-based monomer which are cured,
- wherein the acrylamide-based monomer is included in an amount of 10 parts by weight to 20 parts by weight based on 100 parts by weight of the acrylate-based binder,
- wherein the acrylamide-based monomer is N,N-dimethylacrylamide, and
- wherein the functional layer has a surface resistance of 1×1013Ω/□ or less and a cross-cut test result of 3B or more when measured for the surface of the functional layer according to the ASTM D3359 standard.
