CARDO-BASED RESIN CAPABLE OF PROVIDING A BLACK PHOTOSENSITIVE RESIN COMPOSITION WITH EXCELLENT PROCESSABILITY, A BLACK PHOTOSENSITIVE RESIN COMPOSITION COMPRISING THE SAME, A COLOR FILTER, AND A LIQUID CRYSTAL DISPLAY DEVICE

摘要

PURPOSE: A cardo-based resin is provided to obtain low dielectric coefficient when used as an alkali-soluble resin of a black photosensitive resin composition.;CONSTITUTION: A cardo-based resin is obtained by a polymerization of a compound which comprises a monomer indicated in chemical formula 1. In chemical formula 1, R1 are the same of different to each other and each of which is independently a functional group indicated in chemical formula 1-a, 1-b, 1-c, 1-d or 1-e. A black photosensitive resin composition comprises an alkali-soluble resin. The alkali-soluble resin(B) is the cardo-resin indicated in chemical formula 2.;COPYRIGHT KIPO 2013
