PHOTOSENSITIVE RESIN COMPOSITION, METHOD FOR MANUFACTURING COLOUR FILTER, COLOUR FILTER AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

A photosensitive resin composition, a method for manufacturing a colour filter, a colour filter and a liquid crystal display device. The photosensitive resin composition comprises an alkali-soluble resin (A), a compound having an ethylenically unsaturated group (B), a photoinitiator (C), a solvent (D) and a pigment (E). The alkali-soluble resin (A) comprises an alkali-soluble resin (A-1) and an alkali-soluble resin (A-2). The alkali-soluble resin (A-1) is obtained by reaction of a mixture. The mixture comprises an epoxy compound having at least two epoxy groups (a-1-1), a compound having at least one carboxylic group and at least one ethylenically unsaturated group (a-1-2), a tetracarboxylic acid or a dianhydride thereof (a-1-3) and a dicarboxylic acid or an anhydride thereof (a-1-4). The epoxy compound having at least two epoxy groups (a-1-1) has a structure as shown by the following formula (aI-1) or the following formula (aI-2). The photoinitiator (C) comprises a photoinitiator (C-1) represented by formula (1).
