Abstract: Disclosed is an optical-filter-cell-array structure and a method of manufacturing the same. An optical filter which includes an optical filter layer for blocking light of a specific wavelength formed on an upper side or a lower side of a tempered glass substrate is provided in the form of a cell array. The method includes forming a sheet-cutting part according to the form of a cell array on a mother glass substrate, tempering the mother glass substrate so that a lateral side of the mother glass substrate is tempered through the sheet-cutting part while an upper side and a lower side of the mother glass substrate are tempered, and forming an optical filter layer on the upper side or the lower side of the mother glass substrate.

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.
