Abstract

A method for forming a resist fine pattern uses inkjet printing for printing an ink along a path to form a resist fine pattern on a substrate having the same surface energy. The method includes an ejecting step of simultaneously discharging a photocurable resist ink and a partition-forming ink that are spaced from each other on the front side and the rear side of the path and applying the light energy to the discharged photocurable resist ink. The intensity of light is set so that, as the photocurable resist ink is semi-cured and is ejected on the substrate in a gelatinous state, the ink forms a boundary that is vertical with respect to the partition-forming ink ejected on the substrate and the spreading of the photocurable resist ink is prevented, and the photocurable resist ink is cured after both the photocurable resist ink and the partition-forming ink are completely ejected.
