Hard coating film and image display device comprising same

Abstract

A hard coating film may include a substrate and a hard coating layer provided on at least one surface of the substrate, in which, when the hard coating film is folded and unfolded 200,000 times with a bending radius of 1 mm in the direction in which the hard coating layer is oriented inwards under 60° C. and 90% relative humidity (RH), breakage does not occur, and the amount of change in transmission b* (chromaticity) of the film after UV irradiation for 100 hr using a 15 W UV-B lamp is 1.5 or less. The hard coating film may exhibit superior anti-curling properties, superior bending resistance under high-temperature and high-humidity conditions, and high light resistance, and can thus be applied not only to an image display device but also to a window for a flexible display device.
