Abstract
A radiation sensitive resin composition for forming a rib comprising (A) a copolymer of (a-1) hexafluoropropylene, (a-2) an unsaturated carboxylic acid and/or unsaturated carboxylic anhydride and (a-3) an unsaturated compound other than the components (a-1) and (a-2), (B) an acid generating compound which generates an acid upon exposure to radiation, (C) a crosslinkable compound and (D) a fluorine-containing organic compound other than the component (A). A rib formed from the composition, a rib forming method, and an organic EL display element and liquid crystal display element having the rib. The rib does not cause a 'satellite' phenomenon when an organic EL layer or ITO transparent electrodes are formed by coating, and an organic EL display element and liquid crystal display element having the rib of the present invention are excellent in productivity and reliability.
