HARD-COATING FILM FOR DISPLAY DEVICE, AND DISPLAY DEVICE COMPRISING SAME

摘要

Provided is a hard-coating film for a display device comprising: a plastic substrate of which the modulus of elasticity is 2.5 GPa and the glass transition temperature is at least 150 degrees; and a hard-coating layer provided on at least one surface of the plastic substrate, and, in the present invention, the plastic substrate has a thickness of no more than 100 μm and comprises: an active energy ray curable resin composition containing a (meth)acrylate polymer (A) having a hydroxyl group and a (meth)acryloyl group and having a weight-average molecular weight (Mw) in a range of between 3,000 to 100,000, and an isocyanate compound (B); and, optionally, nano-sized inorganic particles dispersed in the resin composition, while the hard-coating film has a pencil hardness of 4H as measured by ASTM D3363 under a weight of 1 kg and has a flexibility of a radius of curvature of 10 mm. Also provided is a display device comprising the hard-coating film.
