| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a method for manufacturing a hologram color filter stable in heat treatment. SOLUTION: The method for manufacturing a hologram color filter 1 includes a process of adhering a transparent glass substrate 2 having a volume hologram which selectively diffracts the wavelength component of the incident light to a thin transparent glass layer 5 with an adhesive and a process of cutting the adhered body into a specified form. In the method, the laminated body after cut is subjected to heat treatment while temperature increase and decrease are repeated plural times in a specified temperature range. |
