HARD COATING FILM WITH HIGH HARDNESS, POLARIZING PLATE AND DISPLAY DEVICE HAVING THE SAME

摘要

A hard coating film with high hardness, a polarizing plate having the same and a display device are provided to secure good high hardness, wear resistance, weather resistance, and optical high transparency and to prevent curling. A hard coating film with high hardness has a hard coating layer formed by spreading hard coating solution containing a UV(Ultraviolet)-curable resin composition, on one surface of a transparent base film. The UV-curable resin composition contains reactive silica particle produced by chemically bonding multi-functional organic matter having a polymer unsaturated group, with a siloxy group formed on the surface of the silica particle. The thickness of the hard coating layer is within a range of 5~30 micrometers and the curling characteristic is below 15mm.
