Abstract
A negative photosensitive resin composition including an alkali-soluble resin (A), a compound (B) containing an ethylenically-unsaturated group, a photoinitiator (C), a solvent (D), and a silicone compound (E) is provided. The silicone compound (E) contains the structure represented by formula (E-1). The negative photosensitive resin composition has good sputtering resistance, by using the negative photosensitive resin composition, the issue of poor sputtering resistance of the spacer or a protective film formed by the negative photosensitive resin composition can be solved.
