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.
