(57) [Abstract] (with correction) [PROBLEMS] A composition for a non-conductive light-shielding layer in which the solubility of an unexposed portion in a developing solution is improved while the development resistance of an exposed portion is maintained, and no foreign matter is attached. Provide non-conductive light-shielding layers and color filters that are excellent in materials, light-shielding ability and blackness. An alkali-soluble binder having an average molecular weight of 2,000 to 20,000, a photopolymerizable monomer, a coating film property improver, a photopolymerizable initiator, at least copper, manganese, A pigment and a solvent, which are composite metal oxide fine particles containing five kinds of metals of iron, zinc and zirconium, are mainly used, and the photopolymerizable monomer is a polyfunctional (meth) acrylate and / or Alternatively, a non-conductive light-shielding layer comprising a linear oligomer having an average molecular weight of 1,000 to 10,000, the above composition is applied to a substrate, dried and subjected to pattern exposure and development to form a pattern. A transparent substrate provided with a black matrix composed of red, green, and blue pixels and the above-mentioned non-conductive light-shielding layer. |
