Abstract
A method of manufacturing a module having multiple pattern areas, a module having multiple pattern areas according to the method, and a method of manufacturing a diffraction grating module or a mold for a diffraction grating module. The method of manufacturing a module having multiple pattern areas comprises: disposing a first substrate having a first pattern on a first base substrate; forming a first cutting line on the first substrate; forming a second cutting line on the first substrate; removing any one of a first area defined by the first cutting line and a second area defined by the second cutting line from the first substrate to form a removed area on the first substrate; disposing a second base substrate having a second pattern different from the first pattern in the removed area; and removing the first substrate from the base substrate without removing the first and second areas.
