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.
