  • POLYIMIDE COVER SUBSTRATE
    Publication number: 20160040027
    Abstract: Disclosed is a polyimide cover substrate, which is configured such that a device protection layer is formed of a urethane acrylate compound on at least one side of a polyimide film, thereby exhibiting not only high flexural properties and impact resistance but also superior solvent resistance, optical properties and scratch resistance and low water vapor transmission rate, and thus can be effectively utilized as a cover substrate for a flexible electronic device.
