To provide a radiation-sensitive resin composition having good sensitivity and excellent temporal stability of sensitivity, a cured film, a pattern forming method, a solid-state image sensor, and an image display device.SOLUTION: The radiation-sensitive resin composition contains a resin, a polymerizable compound having an ethylenically unsaturated bond, a photopolymerization initiator, an organic solvent, and water. The photopolymerization initiator contains an oxime ester compound having at least one group selected from a branched alkyl group and a cyclic alkyl group. The content of the water is 0.1-2 mass% based on the mass of the radiation-sensitive resin composition.SELECTED DRAWING: None
