摘要： A negative resist composition used in a liquid-crystal display element is disclosed. The negative resist composition according to the present invention includes a binder resin consisting of a copolymer including four predetermined monomers, a (meth)acryl monomer including at least 3 (meth)acryl groups, a (meth)acryl monomer including one or two (meth)acryl groups and a photo-initiator. The negative resist composition according to the present invention may be useful to significantly increase the manufacturing yield because it shows an extremely low brittleness during a bonding process or a hot process due to good physical properties such as film retention, pattern stability, adhesion to a substrate, and chemical resistance, as well as good flexibility upon formation of the pattern.
