PURPOSE: A negative photosensitive resin composition, a black matrix containing the composition and its preparation method are provided, to improve the heat resistance, the chemical resistance, the optical density, the developing property, the low reflectivity and the surface smoothness. CONSTITUTION: The negative photosensitive resin composition comprises 0.5-10 parts by weight of a heat resistant black pigment; 1-20 parts by weight of an alkali-soluble resin binder; 1-20 parts by weight of a polymeric compound having ethylenically unsaturated bonds; 0.5-10 parts by weight of a photopolymerization initiator or a photoinitiator; and 40-97 parts by weight of a solvent. Preferably the black pigment is at least one selected from the group consisting of graphite, iron oxide, cobalt black, manganese black, titanium black and black-colored glass or ceramic.
