The present invention is to provide a negative-working light-sensitive resin composition having well-balanced properties among sensitivity resolution (whole pattern) tranceparency thermal resistance and resistance to chemicals, and is also to provide a display element using the resin composition. The resin composition of the present invention comprises: [A] alkali-soluble resin obtained by copolymerizing (a-1) an unsaturated carboxylic acid and (a-2) a radically polymerizable compound represented by the following formula (I): wherein R1 to R3 in the formula each independently represents a hydrogen atom or an alkyl group having from 1 to 5 carbon atoms. R4 represents a hydrogen atom or an alkyl or alkoxy group having from 1 to 5 carbon atoms and m represents an integer of from 1 to 5: [B] a compound having at least one ethylenically unsaturated double bond: and [C] a photopolymerization initiator. The present invention also relates to a display element using the resin composition.
