Abstract:
1. A photosensitive resin composition for simultaneously forming two isolated forming two isolated patterns using a half-tone mask, the photosensitive resin composition comprising at least one radical polymerization inhibitor selected from the group consisting of compounds having two or more phenolic hydroxyl groups, compounds having at least one aromatic ring substituted with at least one imino group, cyclic compounds partially substituted with at least one imino group, and hindered amine compounds; an alkali-soluble resin; an ethylenically unsaturated compound; a photoinitiator; and a solvent, wherein the two isolated patterns are a saturated pattern and a semi-transmissive pattern, and the ratio of the thickness of the semi-transmissive pattern to the thickness of the saturated pattern is 0.3˜0.9, and wherein the radical polymerization inhibitor is present from 0.0001 to 5% by weight, based on the total weight of the photosensitive resin composition.
