  • Patent number: 11634555
    Abstract: A colored resin composition containing an alkali-soluble resin (A), a colorant (B), an organic solvent (C), and a photosensitizer (D), the colored resin composition containing at least a zirconia compound particle as the colorant (B), wherein the zirconia compound particle contains zirconium nitride having a crystallite size of 10 nm or more and 60 nm or less, and the crystallite size is determined from a half width of a peak derived from a (111) plane in an X-ray diffraction spectrum using a CuK? ray as an X-ray source. The present invention provides a highly sensitive colored resin composition by improving light transmissivity in the ultraviolet region (wavelength 365 nm) generally used in photolithography and by improving a light shielding property in the visible region.

  • Publication number: 20230097238
    Abstract: An organic EL display device including a substrate, and a planarization layer, a first electrode, a pixel division layer, a light emitting pixel and a second electrode formed on the substrate, wherein the planarization layer and/or the pixel division layer contain(s) zirconium nitride particles, and a crystallite size of the zirconium nitride particles determined from a half width of a peak derived from a (111) plane in an X-ray diffraction spectrum using a CuK? ray as an X-ray source is 5 nm or more 20 nm or less. Provided are an organic EL display device with excellent visibility and fewer display defects, and a cured film which is excellent in storage stability of a photosensitive resin composition capable of being applied on an insulating layer of the organic EL display device, and which has high sensitivity and high visible light-shielding property and is also free from residue in the opening.

  • Publication number: 20180039176
    Abstract: A colored resin composition is disclosed including a polyimide resin having a specified structure to achieve remarkable heat resistance and enabling the formation of a colored film which is excellent in reliability because a coloring material is highly dispersed and stabilized therein. A colored resin composition is disclosed including (A) an alkali-soluble polyimide resin having a structural unit containing a phenolic hydroxyl group, a sulfonic acid group or a thiol group, (B) a coloring material, (C) a polymeric dispersant, and (D) an organic solvent. A patterned colored layer obtained from the composition of the present invention is useful for a decorative substrate, a touch panel, an organic EL display device and the like.

  • Patent number: 9261633
    Abstract: Disclosed is a black resin composition with which a black matrix having high insulation properties even after heat treatment at a high temperature and, in addition, achromatic reflection properties can be readily formed. The black resin composition comprises (A) a light-shielding material, (B) an alkali-soluble resin, and (C) an organic solvent, and comprises (A-1) a carbon black and (A-2) titanium nitride compound particles as the light-shielding material (A). The carbon black (A-1) is surface-treated with a sulfur-containing compound, and in the surface composition, the percentage of carbon atoms is 95% or less and the percentage of sulfur atoms is 0.5% or more.
