To provide a dispersion containing organic pigment nanoparticles having a sharp peak of particle size distribution of nanometer size and a method for manufacturing the same, inkjet ink having high stability which can suitably be used for manufacturing a color filter using the same, a colored photosensitive resin composition and a photosensitive resin transfer material, and to provide a color filter having high contrast and expressing excellent display properties using the same, liquid crystal display and a CCD device having excellent image reproducibility.
The organic pigment nanoparticle dispersion comprises nanoparticles of an organic pigment in which the contents of alkali or alkali earth metal in the dispersion are regulated to 0.001-500 ppm.
