More Information
Summary:A method of manufacturing a color filter, includes forming a colored coated film on a substrate using a colored composition containing a pigment, a monomer having an ethylenic unsaturated double bond and photo-polymerization initiator, irradiating a filter segment-forming region or a black matrix-forming region of the colored coated film with an excimer laser beam having a wavelength of 308 nm (XeCL) at a dosage sufficient to achieve a cumulative light exposure of 1-150 mJ/cm2, thereby curing the irradiated region, removing uncured portions of the colored coated film to form the filter segment or the black matrix, and repeating the above-described steps plural times, thereby forming filter segments of at least two colors and/or a black matrix.
