Claim Text:
1. A positive photosensitive resin composition, comprising: (A) a polybenzoxazole precursor including a first polybenzoxazole precursor including a repeating unit represented by the following Chemical Formula 1 and a repeating unit represented by the following Chemical Formula 2, and a repeating unit represented by the following Chemical Formula 32 and having a thermally polymerizable functional group at least one terminal end; (B) a photosensitive diazoquinone compound; (C) a silane compound; (D) a phenol compound; and (E) a solvent: wherein in Chemical Formulae 1, 2, and 32, X X wherein in Chemical Formulae 6 and 9 to 13, R R n9, n11 and n13 are each independently integers ranging from 1 to 5, and n6, n10, n12, n14, n15 and n16 are each independently integers ranging from 0 to 3, X Y wherein the first polybenzoxazole precursor comprises about 5 parts by mole to about 40 parts by mole of the repeating unit reoresented by Chemical Formula 2 and about 5 parts by mole to about 40 parts by mole of the repeating unit represented by Chemical Formula 32, based on 100 parts by mole of the repeating unit represented by Chemical Formula 1.
