Patent ID: 8921019

Claim:
A positive photosensitive resin composition, comprising (A) an alkali soluble resin including a polybenzoxazole precursor, a polyimide precursor, or a combination thereof; (B) a photosensitive diazoquinone compound; (C) a phenol compound; (D) at least one organic dye having an absorption wavelength of about 400 to about 700 nm; and (E) a solvent, wherein the organic dye (D) is included in an amount of about 1 to about 40 parts by weight based on about 100 parts by weight of the alkali soluble resin (A) and wherein the organic dye (D) comprises a methine-based compound represented by the following Chemical Formula 28: wherein, in Chemical Formula 28, R 43 to R 46 and R 53 to R 56 are the same or different and are each independently hydrogen, halogen, substituted or unsubstituted C1 to C20 alkyl, substituted or unsubstituted C1 to C20 haloalkyl, substituted or unsubstituted C1 to C20 alkoxy, substituted or unsubstituted C2 to C20 alkenyl, substituted or unsubstituted C2 to C20 alkynyl, substituted or unsubstituted C3 to C20 cycloalkyl, substituted or unsubstituted C3 to C20 cycloalkenyl, substituted or unsubstituted C3 to C20 cycloalkynyl, substituted or unsubstituted C2 to C20 heterocycloalkyl, substituted or unsubstituted C2 to C20 heterocycloalkenyl, substituted or unsubstituted C2 to C20 heterocycloalkynyl, substituted or unsubstituted C6 to C30 aryl, or substituted or unsubstituted C2 to C30 heteroaryl, R 47 , R 48 , R 50 and R 51 are the same or different and are each independently hydrogen or substituted or unsubstituted C1 to C20 alkyl, R 49 and R 52 are the same or different and are each independently hydrogen, substituted or unsubstituted C1 to C20 alkyl, substituted or unsubstituted C1 to C20 alkyl(meth)acrylate, or substituted or unsubstituted C6 to C30 aryl, n is an integer ranging from 1 to 4, and A is halogen, ClO 4 − , BF 4 − , SbF 6 − , CF 3 SO 3 − or N(SO 2 CF 2 ) 2 − .
