Abstract
A color filter manufacturing apparatus of this invention includes a plurality of ink-jet heads (120a, 120b, 120c) each having a first ink discharging nozzle group (108) in which the pitch of a plurality of ink discharging nozzles in the Y-axis direction is set to be equal to the pitch of pixels of the same color in the Y-axis direction, and a second ink discharging nozzle group having a nozzle pitch set to be equal to the pixel pitch in the Y-axis direction like the first ink discharging nozzle group. Control of an ink discharging operation is performed for only one of the first and second ink discharging nozzle groups which is to be used to color pixels of corresponding colors on a substrate (1).

59. A method of manufacturing a color filter having a plurality of colored pixels on a substrate by discharging an ink from an ink-jet head having a plurality of ink discharging nozzles while performing relative movement of said ink-jet head and the substrate, comprising the steps of:
-
dividing the plurality of ink discharging nozzles for discharging an ink having a same color into a plurality of nozzle groups;
coloring the pixels of one substrate by using only one nozzle group in the plurality of nozzle groups for the same color; and
switching from the one nozzle group to an other nozzle group as a nozzle group to be used for the same color, wherein an operation of the switching in said switching steps is not performed during coloring the one substrate. - View Dependent Claims (60)

62. A method of manufacturing a color filter having a plurality of colored pixels on a substrate, comprising the steps of:
-
performing relative movement of the substrate and ink-jet heads corresponding to different colors, each of the ink-jet heads having a plurality of nozzle groups corresponding to a same color, each of the nozzle groups comprising a plurality of ink discharging nozzles;
forming the colored pixels having different colors by discharging different color inks from respective nozzle groups for respective different colors onto the pixels of the substrate while performing relative movement of the substrate and said inkjet heads a plurality of times; and
switching, for respective different colors, from the one nozzle group to an other nozzle group as a nozzle group to be used, wherein, in coloring one substrate by plural relative movements in said forming step, inks having different colors are discharged by using only one nozzle group of respective nozzle groups for respective different colors in the plural relative movements, and wherein an operation of the switching in said switching step is not performed during coloring of the one substrate. - View Dependent Claims (63, 64)

65. A method of manufacturing a color filter having a plurality of colored pixels on a substrate by discharging an ink from an ink-jet head having a plurality of ink discharging nozzles while performing relative movement of the ink-jet head and the substrate, comprising the steps of:
-
dividing the plurality of ink discharging nozzles for discharging an ink having a same color into a plurality of nozzle groups, the plurality of nozzle groups including at least a first nozzle group and a second nozzle group;
coloring the pixels of one substrate by using only the first nozzle group for the same color;
switching from the first nozzle group to the second nozzle group as a nozzle group to be used for coloring the pixels;
adjusting relative positions of the pixels of the substrate and the nozzles of the second nozzle group; and
coloring the pixels of an other substrate by using only the second nozzle group for the same color, wherein an operation of the switching in said switching step is not performed during coloring of the substrate. - View Dependent Claims (66, 67)
