Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a photosensitive resin composition for spacers having a satisfactory process margin, capable of suppressing contamination of a kiln, a photomask, etc., due to sublimation of a photopolymerization initiator component, causing no in-liquid foreign substance, and capable of easily forming spacers excellent in the shape of a cross section and in various performances such as compressive strength, rubbing resistance and adhesion to a transparent substrate, spacers formed of the composition, a method for forming the same, and a liquid crystal display panel having the spacers. SOLUTION: The photosensitive resin composition contains as essential components [A] a copolymer of (a1) an unsaturated carboxylic acid and/or an unsaturated carboxylic acid anhydride, (a2) a specific monomer having an oxetanyl group, and (a3) an ethylenically unsaturated compound other than the components (a1) and (a2), [B] a polymerizable compound having an ethylenically unsaturated bond, and [C] a specific photopolymerization initiator.
