Ink composition for a color filter, a color filter substrate manufactured using the ink composition and method of manufacturing a color filter substrate using the ink composition

摘要

An ink composition for a color filter includes about 100 parts by weight of a pigment dispersion, about 7 parts by weight to about 65 parts by weight of a thermosetting resin having hydroxyl group at a side chain of the thermosetting resin, about 0.015 part by weight to about 1.5 parts by weight of a thermal initiator, about 0.8 part by weight to about 15 parts by weight of an epoxy-based resin containing fluorine, and about 15 parts by weight to about 165 parts by weight of a solvent. A color filter substrate is manufactured using the ink composition for color filter. The ink composition for the color filter improves straightness of ink jetting through an ink-jetting nozzle and prevents the ink composition from spreading to neighboring pixels.
