Abstract
The present invention provides a negative type colored photosensitive resin composition that serves to produce a cured film having a forward tapered shape. This negative type colored photosensitive resin composition includes an alkali-soluble resin (A), a photo initiator (B), a photo polymerizable compound (C), and a coloring agent (D), the alkali-soluble resin (A) containing a polyimide precursor, polybenzoxazole precursor, and/or a copolymer thereof (A-1), each resin (A-1) having a trifluoromethyl group in the backbone chain.
