Abstract
Flexible display devices, such as flexible cover lens films, are discussed and provided herein. The flexible cover lens film has good strength, elasticity, optical transmission, wear resistance, and thermostability. The cover lens film includes a hard coat layer with a thickness from about 5 μm to 40 μm, an impact absorption layer with a thickness from about 20 μm to 110 μm, and a substrate layer with a thickness from about 10 μm to 175 μm and is disposed between the hard coat layer and the impact absorption layer. By combining the hard coat layer and the impact resistant layer, the cover lens film is both flexible and strong with hardness from 6H to 9H.
