Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an optical filter used for a display device and including a color correction function layer and/or a near infrared light cut function layer, the optical filter being manufactured by the streamlined manufacturing process of the color correction function layer and/or the near infrared light cut function layer, therefore being suitable for use in a variety of models of display devices each requiring small number of the filters, i.e., suitable for high-mix low-volume production, and having little hue spots. SOLUTION: The optical filters are characterized in that the color correction function layer and/or the near infrared light cut function layer are formed by sublimation transfer of sublimation dye.
