Abstract

The resin composition of the present invention is a resin composition characterized by including (a) a polyimide, a polybenzoxazole, a polyimide precursor or a polybenzoxazole precursor, (b) 1,5-dihydroxynaphthalene, 1,6-dihydroxynaphthalene, 1,7-dihydroxynaphthalene, or 2,3-dihydroxynaphthalene, and (c) a thermal cross-linking agent having a specific structure. By the use of the resin composition of the present invention, it is possible to reduce the transmittance in the visible region of a cured film while maintaining the transmittance of a resin film before curing.
