BLUE DYE COMPOUND, BLUE RESIN COMPOSITION FOR COLOR FILTER CONTAINING SAME AND COLOR FILTER USING SAME

摘要

Disclosed is a blue dye compound for a color filter represented by Chemical Formula 1. The blue colored resin composition including the blue dye compound has excellent solubility to an organic solvent, such as propylene glycol methyl ether acetate (PGMEA), excellent miscibility with the other dyes or pigments and high heat resistance. Therefore, when using the blue dye compound, it is possible to obtain a color filter having high luminance and contrast.
