<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of color filter substrate which can make transmission brightness of a color filter uniform in a region divided by barrier walls. <P>SOLUTION: The conductive barrier walls 2 are formed on a substrate 1; an ink (i) that contains pigment having a polarity is disposed on the region 3 divided by the barrier walls 2 and, thereafter, the ink (i) is dried to form the color filter layer 4 while applying a voltage to the barrier walls 2 and charging the barrier walls 2 into the polarity opposite to that of the pigment. According to the method, although the thickness of the color filter layer 4 becomes thinner on the periphery part than on the center part, the pigment is drawn near the charged barrier walls 2 and, thereby, pigment concentration in the color filter layer 4 becomes higher on the periphery part than on the center part. Accordingly, the transmission brightness of a color filter layer 4 can be made uniform in the region 3. <P>COPYRIGHT: (C)2007,JPO&INPIT |
