A photosensitive resin composition includes an alkali-soluble resin (A), a compound having an unsaturated vinyl group (B), a photo initiator (C), solvent (D) and a silane compound (E) having a structure shown as formula (I): in the formula (I), A individually and independently represents a single bond, an alkylene group, or an arylene group, B individually and independently represents an organic group having diphenyl phosphine, hydrogen atom, an alkyl group, an aryl group, or —OR, in which R is a C1-C6 alkyl group or a phenyl group, at least one B is the organic group having diphenyl phosphine and at least one B is —OR. When B is —OR, A connected to B is the single bond. A film formed by the photosensitive resin composition has good refractivity and adhesivity to molybdenum.
