摘要:
A color-filter manufacturing method which manufactures a color filter where occurrence of color mixture and colorless portion(s) are prevented while improving ink-arrival precision in applying ink onto a substrate. The method manufactures a color filter by discharging ink from an ink-jet head IJH on a substrate 53 so as to color respective pixels with a plurality of discharge ink. When ink I2 discharged from the ink-jet head IJH is applied not in the form of ink droplet but in the form of pillar onto the substrate 53, the ink I2 is applied at a position within a pixel, where the ink I2 is to mix with previously-applied ink I1.

Disclosed is an apparatus for automatically measuring the amount of ink discharged from an inkjet printhead. A predetermined amount of pure water is injected into a measurement bottle, the bottle is supplied via an insertion port to a rotary table for measurement purposes, and the rotary table is rotated by 90.degree. to bring the bottle to a point immediately underlying a nozzle of the inkjet printhead. Ink is then discharged into the bottle from the printhead under set measurement conditions. The rotary head is then rotated a further 90.degree. to bring the bottle to a point in front of a photometer. At this time the ink solution is stirred thoroughly and the absorbance thereof is measured by the photometer. When measurement is completed, the rotary table is rotated a further 90.degree. to discard the bottle from a discharge port. These steps are automated by computer control.

A method for forming spacers according to the present invention is a method for forming the spacers on a substrate, comprising the steps of: supplying adhesive at a position for forming each of the spacers on the substrate by an inkjet system; dispersing beads, each bead having a diameter corresponding to the height of the spacer, so as to adhere the beads to adhesive; and removing the beads that are not adhered to the adhesive from the substrate. A manufacturing method for a color filter having spacers according to the present invention, the method comprises the steps of: forming a color filter by forming on a substrate at least a light-shielding layer having plural apertures and a colored layer having colored portions arranged in each of the apertures of the light-shielding layer; supplying adhesive made of a curable resin composition in regions overlapping the light-shielding layer on the color filter by an inkjet system; dispersing beads on the color filter so as to stick the beads to the adhesive; and removing the beads that are not adhered to the adhesive from the color filter. Furthermore, a liquid crystal element according the present invention comprises: a pair of substrates; and liquid crystal clamped between the pair of substrates, wherein one of the pair of substrates is a color filter having spacers made by the above-mentioned manufacturing method and the distance between the pair of substrates is maintained by the spacers.

A width A of the scanning area of the ink ejection orifices and a width B of the scanning area of the reacting liquid ejection orifices are respectively set as A=(n−a)×p and B=n×p, while amount of the feeding of the printing sheet during each scan corresponds to the width of the scanning area of the reacting liquid ejection orifices, that is, A=(n−a)×p. With this system, the width of the scanning area, wherein ejection of the reacting liquid precedes ejection of the ink, is made shorter by C=a×p than the width of following scanning area; the scanning area having the width C is scanned two times by the row of the ink ejection orifices, and the thinning process is applied to this area having the width C.
