Abstract

Disclosed is a glass-based flexible cover window with improved strength including a planar portion formed so as to correspond to a planar region of a flexible display and a folding portion formed so as to be connected to the planar portion, the folding portion being formed so as to correspond to a folding region of the flexible display, wherein the flexible cover window includes a glass substrate, an adhesive buffer layer formed on the glass substrate, a protective film layer formed on the adhesive buffer layer, and a hard coating layer formed on the protective film layer. The protective film layer is formed on the glass substrate, whereby strength and folding characteristics of the flexible cover window are improved, and inherent texture of glass is maintained while the overall thickness of the flexible cover window is reduced, and therefore aesthetics of the flexible cover window are improved.
