(57) Abstract: A novel photosensitive resin composition for forming a spacer for a liquid crystal display element by photolithography is provided. Specifically, the present invention provides a negative-type photosensitive resin composition which has the conventional characteristics, is highly sensitive, has no development residue (scum), has excellent developability, alkali resistance, and water resistance and is suitable as a material for forming a spacer. And a spacer and a liquid crystal display device formed of the resin composition. SOLUTION: An alkali-soluble resin [A], a compound [B] having at least one unsaturated double bond, an organic peroxide photopolymerization initiator [C] having a benzophenone structure, and 4,4'-bis (dialkyl) An amino-insoluble vinyl copolymer [A IS ] containing a photosensitizer [D] having an amino) benzophenone structure and optionally having an epoxy group And a spacer formed of the composition, and a liquid crystal display device including the spacer. |
