Abstract:
A manufacturing method of liquid crystal display device, including:a step for preparing a first substrate having a first main surface on which color filters are farmed, a step for bonding the first substrate and a second substrate having a second main surface with a sealing material at respective peripheries of the first and second substrate being superposed one another so that the first main surface and the second main surface are spaced from and opposite to one another, and a step for injecting liquid crystal substances into a space enclosed by the first and second main surfaces and the sealing material, wherein the color filters are formed by coloring dyed media provided on the first main surface with ink, the ink includes dye for coloring the dyed media, solvent having affinity for the dye, a volatility-adjusting agent lowering volatility of the ink below that of the solvent, and a dyeing-promoter agent indicating higher affinity for the dye and the dyed media than to the volatility-adjusting agent, and concentration of the dye in the ink lies-in a range from 1 to 5 weight percent thereof; concentration of the volatility-adjusting agent therein lies in a range from 1 to 40 weight percent thereof, and concentration of the dyeing-promoter agent therein lies in a range from 1 to 30 weight percent thereof, respectively.
