The present invention provides a photosensitive composition, a photosensitive resin transfer film comprising the photosensitive composition, a method for making the photosensitive partition column using the material, a liquid crystal display device substrate comprising the photosensitive partition column, and a liquid crystal display device comprising the liquid crystal display device, the photosensitive composition at least includes the resin (A), the polymerized compound (B), and the photopolymerization initiating agent (C), the resin (A) includes the group which comprises branched chain and/or alicyclic structure at the side chain, the group which comprises acidic groups at the side chain, and the group which comprises the ethylenically unsaturated groups at the side chain. According to the invention a photosensitive composition which has a high deformation recovery character and can eliminate the display nonuniformity in the liquid crystal display device and the photosensitive resin transfer film, the met
