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.

Hard coating film and image display device comprising same

A flexible window stack structure includes a substrate, a first hard coating layer formed on a surface of the substrate and a second hard coating layer formed on an opposite surface of the substrate. The first hard coating layer has a curing contraction greater than that of the second hard coating layer, and the second hard coating layer is disposed at an elongated side when the window stack structure is folded. Cracks may be prevented by a curl property of the first hard coating layer when being bent.

The present invention relates to a hard coating film and an image display apparatus comprising same, the hard coating film having a hard coating layer formed on at least one surface of a polyimide-based substrate, the hard coating layer comprising the cured product of a hard coating composition, wherein the hard coating composition comprises a solvent for swelling a polyimide-based resin, and the hard coating film is configured such that when the reflectivity thereof is measured in the range of 400 nm to 800 nm, the maximum amplitude difference in the oscillations of the reflectivity is controlled at 0.5% or less, and thus can prevent an interference pattern.

Hard coating film and image display apparatus comprising same

The pharmaceutical composition of the present invention, which comprises spinosin or a spinosin-containing herbal extract, is a composition for preventing and treating cognitive function disorders, and can effectively improve memory and learning ability, and effectively treat and prevent cognitive function disorders such as dementia and amnesia.

A portable terminal and a method for providing network contents using the portable terminal are provided. The portable terminal receives contents from a network, uses information related to a destination and a pre-stored map data to search for a travel route from a start point to the destination, determines an estimated time for a user to reach the destination from the start point, and outputs travel guide information to guide the user along the travel route while outputting contents having a reproduction time corresponding to the estimated time.
