  • Patent number: 7948697
    Abstract: A color filter including: a transparent substrate; a light shielding part formed on the transparent substrate and contains at least a light shielding material and a resin; and a colored layer formed in the opening part of the light shielding part on the transparent substrate to cover a part of the light shielding part. The light shielding part has: the width of the thick film region, 85% of more of the maximum film thickness of the light shielding part and disposed in the central part of the light shielding part, in a range of 30% to 60% of the light shielding part line width; and the width of each of the thin film regions, 50% or less of the maximum film thickness of the light shielding part and disposed on the both side parts of the light shielding part, in a range of 10% to 20% of the light shielding part line width.

  • Patent number: 7785501
    Abstract: A black resin composition for a display device, which can achieve a high optical density even when its light-blocking agent content is relatively low and can achieve a high optical density even when it is formed into a thin film, and a member for display device which can reduce unevenness of display caused by a level difference in a pixel part resulting from the film thickness of the black resin composition. The black resin composition for a display device has a black titanium oxynitride represented by composition formula: TiNxOy-nSiO2 (wherein x and y each are a real number of larger than 0 but less than 2, and n is a real number within the range of 0 less than or equal to n less than or equal to 0.05), containing a nitrogen atom represented by N in an amount of 17 wt % or more but less than 23 wt %, and having a specific surface area of 5 to 30 m2/g and a crystalline size as measured with an X-ray diffractometer of 17 to 25 nm, and a curable binder system.
