Abstract:
An ink-jet head in which a plurality of ink discharge nozzles are arrayed in a lengthwise direction, used in a method for manufacturing a color filter, which has a substrate and a plurality of color filtering portions divided by a plurality of black matrix lines each of which has a predetermined width, by scanning said ink-jet head relatively to the substrate while performing coloring by discharging ink from said ink-jet head,wherein a width GL which is a distance between centers of two adjacent said black matrix lines arrayed in a direction orthogonal to a scanning direction, an ink dot diameter CL formed after an ink is applied onto the substrate, an acute slant angle .theta. of said ink-jet head in a direction orthogonal to the scanning direction, and a nozzle shift width y in a direction orthogonal to an ideal straight line where the plurality of ink-discharge nozzles are arrayed if said ink-jet head is not warped, satisfyy.ltoreq.(GL-CL)/sin.theta. (0.degree.<.theta.<90.degree.)when said ink-let head is warped.
