Provided is a method of manufacturing a partition wall that is excellent in the uniformity of the thickness of the ink layer even when the exposure amount in the exposure step is low. Fluoropolymer having a side chain having a fluoroalkyl group (wherein the alkyl group may have an etheric oxygen atom between carbon atoms) and a side chain having an ethylenic double bond (A ), A step of applying a negative photosensitive composition to a substrate, a drying step, an exposure step, and a development step in that order, followed by a post-exposure step. |
