Color red pigment dispersion and a method for producing the same filter, a red photosensitive resin composition and a production method thereof for a color filter, a color filter, a liquid crystal display device, and an organic light emitting display device

A excellent in dispersibility and dispersion stability, in particular to achieve high brightness, and red pigment dispersion and a method for producing the same color filter also achieves demand for high contrast, excellent in dispersibility and dispersion stability, particularly to achieve high brightness, further capable of forming a high contrast color layer, and provides an excellent color filter for red-sensitive resin composition, and a method of manufacturing the same alkali developability. A red pigment having an A anthraquinone skeleton, a sulfonated derivative of a yellow pigment, a pigment dispersing agent is a block copolymer comprising a salt of tertiary amine, containing a solvent, a red pigment dispersion for a color filter a color filter red-sensitive resin composition comprising a liquid and the pigment dispersion and photosensitive binder component. .BACKGROUND
