Method for producing a color filter, apparatus for manufacturing a color filter, electrooptic apparatus, and electronic device

Abstract

An apparatus for manufacturing a color filter includes a stage on which a base having a target discharge area is adapted to be placed, a plurality of discharge heads having a first discharge head filled with a functional material, and a second discharge head filled with a liquid, and a control unit operatively coupled to the stage and the plurality of discharge heads. The control unit controls the stage and the plurality of discharge heads such that the stage and the plurality of discharge heads move relative to each other and a droplet of the functional material from the first discharge head and a droplet of the liquid from the second discharge head are discharged in the same target discharge area. The surface tension or viscosity is lower than that of the functional material.

1 . An apparatus for manufacturing a color filter comprising:
 a stage on which a base having a target discharge area is adapted to be placed;   a plurality of discharge heads having a first discharge head filled with a functional material, and a second discharge head filled with a liquid whose surface tension or viscosity is lower than that of the functional material; and   a control unit operatively coupled to the stage and the discharge heads, the control unit being configured to control the stage and the discharge heads such that the stage and the discharge heads move relative to each other and a droplet of the functional material from the first discharge head and a droplet of the liquid from the second discharge head are discharged in the same target discharge area.   
   
   
       2 . The apparatus for manufacturing a color filter according to  claim 1 , wherein
 the control unit is configured to control the stage and the discharge heads such that the liquid is discharged from the second discharged head before the droplet of the functional material is discharged from the first discharge head.   
   
   
       3 . The apparatus for manufacturing a color filter according to  claim 1 , wherein
 the control unit is configured to control the stage and the discharge heads such that the liquid is discharged from the second discharge head toward an edge portion of the target discharge area on the base.   
   
   
       4 . The apparatus for manufacturing a color filter according to  claim 1 , wherein
 the liquid is a solvent for the functional material.   
   
   
       5 . The apparatus for manufacturing a color filter according to  claim 4 , wherein
 the liquid includes a high boiling point solvent for the functional material, the high boiling point solvent having a boiling point of 250° C. or higher at one atmospheric pressure, and   the functional material includes coloring ink.   
   
   
       6 . The apparatus for manufacturing a color filter according to  claim 3 , wherein
 the control unit is configured to control the stage and the discharge heads such that the liquid is discharged from the second discharge head only toward the edge portion of the target discharge area on the base.   
   
   
       7 . The apparatus for manufacturing a color filter according to  claim 1 , wherein
 the surface tension of the liquid is lower than that of the functional material.
