  • Colored composition, color filter and manufacturing method thereof
    Patent number: 8216750
    Abstract: 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.

  • Colored composition, color filter and method of manufacturing the same
    Publication number: 20100253888
    Abstract: Disclosed is a coloring composition including a pigment, a transparent resin, a monomer having an ethylenic unsaturated double bond, and a photo-polymerization initiator, wherein a ratio (M/P) of weight (M) of the monomer having an ethylenic unsaturated double bond to weight (P) of the transparent resin is confined to a range of 0.12 to 1.35, and the coloring composition is adapted to be employed in a manufacturing method of a color filter including coating a surface of a substrate with the coloring composition, irradiating a filter segment-forming region or a black matrix-forming region of the coated coloring composition film with a laser beam having a wavelength of 340 nm to 380 nm, thereby curing the irradiated region, and removing uncured portion of the coated coloring composition film to form the filter segment or the black matrix.
