description PROBLEM TO BE SOLVED: To suppress slant angle variation of a diffraction grating constituting a hologram color filter due to heating added in a manufacturing process of a spatial optical modulation element. SOLUTION: The stable hologram color filter without slant angle variation of the diffraction grating in a heating process is provided by arranging a hologram lens layer going >=1.5 mm inward from the edges of a supporting glass substrate and by using an adhesive with a glass transition temperature >=50 deg. higher than the heating temperature added in the manufacturing process of the spatial optical modulation element as the adhesive layer covering the hologram lens layer.
