Abstract:
A color filter ink set is adapted to be used to manufacture a color filter by an inkjet method. The color filter ink set includes a plurality of inks with each of the inks including a colorant and a liquid medium that disperses and/or dissolves the colorant. The inks include a green ink having C. I. Pigment Green 58 and a substance represented by a prescribed chemical formula. A viscosity at 25° C. of the liquid medium of the green ink is lower than a viscosity at 25° C. of the liquid medium of the ink other than the green ink. A difference (ηmax−ηmin) between a viscosity (ηmax (mPa·s)) of the ink having the highest viscosity among the inks at 25° C. and a viscosity (ηmin (mPa·s)) of the ink having the lowest viscosity among the inks at 25° C. is 1.0 mPa·s or less.
