Abstract: Disclosed are a flexible cover window and a method of manufacturing the same. A glass-based flexible cover window includes planar portions formed so as to correspond to planar regions of a flexible display and a folding portion formed so as to be connected to the planar portions, the folding portion being formed so as to correspond to a folding region of the flexible display, wherein the folding portion including a shock compensation pattern unit, and the shock compensation pattern unit has cylindrical patterns.

A glass-based flexible cover window includes planar portions formed so as to correspond to planar regions of a flexible display and a folding portion formed so as to be connected to the planar portions, the folding portion being formed so as to correspond to a folding region of the flexible display, the folding portion having a smaller thickness than each of the planar portions, wherein the flexible cover window includes a glass substrate and a shock compensation pattern unit formed on the glass substrate, the shock compensation pattern unit is formed at each of the planar portions and the folding portion, and the shock compensation pattern unit has cylindrical patterns.

Abstract: A method of manufacturing a flexible cover window is proposed. The flexible cover window includes a planar part and a folded part extending continuously from the planar part, wherein the folded part is thinner than the planar part. The method includes: forming a photoresist layer on a glass substrate, patterning the photoresist layer to form a gradation resist pattern layer for forming the folded part on the glass substrate, forming the folded part having an inclined portion formed between the folded part and the planar part using the gradation resist pattern layer as a mask, removing the gradation resist pattern layer, and reinforcing the glass substrate.
