OPTICAL FILM FOR COLOR CORRECTING OF LIGHT AND MANUFACTURING METHOD THEREOF

PURPOSE: An optical film for color correcting of light and a manufacturing method thereof are provided to let the light emitted from light-emitting elements pass through a microlens array, thereby correcting the light as a desired chromaticity. CONSTITUTION: An optical film(1) for color correcting of light comprises a film substrate(2) and a microlens array(3). The microlens array is arranged on one surface of the film substrate. The film substrate is made of polyethylene terephthalate and molded into a sheet shape. The microlens array is composed by arranging and connecting multiple hemispherical structures of color fixation composites in a plane. Color grading agents are included in the color fixation composites so that the light emitted from light-emitting elements is corrected as desired by moving to the desired chromaticity coordinates, while passing through the microlens array.
