PROBLEM TO BE SOLVED: To substantially prevent the adhesion of ink on projecting parts and to substantially prevent the occurrence of the loss of colors within pixels as the spreading of the ink in recessed parts is excellent by using a substrate subjected to the surface treatment at the recessed parts by a lipo-ink treating agent. SOLUTION: The projecting parts 2 imparted with an adequate ink repulsive property, more preferably the projecting parts 2 by a black mask are previously formed atop 4 the substrate 1 to impart the affinity to the recessed parts 3 segmented by the projecting parts 2. The colored ink is sprayed by an ink jet system to form colored layers 6, by which the color filters are formed. If the entire protective film of the projecting parts 2 has the strong ink repulsion property and the recessed parts 3 do not have the strong lipo-ink property, the sprayed ink is repulsed by the projecting parts 2 and the central parts of the recessed parts 3 are made thick but the ink does not sufficiently adhere to the peripheral parts and these parts are formed thinner. While the lipo-ink treating agent varies with the properties of the ink to be used, a hydrophilic silicone compd. and fluorinecontained compd. are preferable when the aq. ink is used. |
