Title: BLUE PHOTOSENSITIVE RESIN COMPOSITION, AND COLOR FILTER AND IMAGE DISPLAY DEVICE MANUFACTURED BY USING SAME
Abstract:
A blue photosensitive resin composition according to the present invention comprises: an alkali soluble resin; a blue colorant; and scattering particles having an average particle diameter of 30-500nm and comprising metal oxide. The alkali soluble resin comprises a cardo-based binder resin comprising at least one repeating unit among chemical formulas (1)-(3). The blue photosensitive resin composition according to the present invention has the advantages of: providing excellent color reproduction properties and high light efficiency; showing excellent heat flow properties and thus showing improved pattern straightness and enhanced process efficiency and not showing reverse taper; not showing after-image when operating a panel; and showing high-quality images and excellent heat resistance, chemical resistance, durability and reliability by means of excellent anti-reflective effects.
