PROTECTIVE FILM

摘要

PURPOSE: A protective film having good UV screening property is provided to prevent aging of the film while minimizing temporal change of electronic ink, and to offer anti-glare function and anti-scratch function. CONSTITUTION: An anti-glare coating layer(1) is formed on a first surface of a first transparent plastic substrate(2) having the first surface and a second surface. A silicon oxide coating layer(3) is formed on the first surface of a second transparent plastic substrate(4). The first transparent plastic substrate and the second transparent plastic substrate are attached through an adhesive layer(5). The silicon oxide coating layer is formed by a vacuum evaporation method.
