AI Technical Summary

Benefits of technology

The present invention provides an ejecting method and apparatus for forming filter elements efficiently with low manufacturing cost. The ejecting method involves using a liquid drop ejecting head with a plurality of nozzles aligned for ejecting a fluid liquid material onto a substance to receive the ejection. The nozzles are disposed in a way that they are in line with the surface of the substance to receive the ejection. The liquid drop ejecting head is moved relatively to the substance to eject the liquid material. The nozzle array is disposed in a way that the nozzles are facing the surface of the substance to eject the liquid material diagonally to the direction of movement. The liquid drop ejecting heads can be disposed in a second direction to eject the liquid material diagonally to the main scanning direction. The shape of the liquid drop ejecting heads can be the same or different. The apparatus includes a liquid drop ejecting head, a holding member, and a moving member. The invention provides a more efficient way to eject liquid materials and reduces costs.

Problems solved by technology

However, there were problems in that manufacturing processes of the photolithography method were complicated and large quantities of coloring materials and photoresist were consumed; thus, manufacturing cost increased.
Thus, there is a problem in that planar translucency of the color filter becomes non-uniform.
However, when a different size of motherboard 301 is used according to the panel area 302, an ink jet head having a different size is necessary for each of the cases; thus, the cost increases.

Embodiment Construction

(Explanation 1 for a Manufacturing Method for a Color Filter and Apparatus Therefor).

[0088] Hereinafter, a basic manufacturing method for a color filter of the present invention and a manufacturing apparatus therefor are explained. Firstly, before explaining the manufacturing method and a manufacturing apparatus using thereof, a color filter which is manufactured by using the above-mentioned manufacturing method is explained. FIG. 5A is a plan view showing an embodiment of the color filter. Also, FIG. 6D is a cross section viewed along a line IV-IV on FIG. 5A.

[0089] In a color filter 1 according to the present embodiment, a plurality of filter elements 3 are formed on a surface of a square base board 2 (which can be called a “base member” in the present invention) which is made from a glass member or a plastic member in a dot pattern such as dot matrix condition in the present embodiment. Furthermore, as shown in FIG. 6D, the color filter 1 is formed by layering a protecting laye...

Abstract

In an ink jet apparatus for manufacturing a color filter 1, ink jet heads 22 having a plurality of nozzle 27 are disposed in a linear manner. Filter element member is ejected to a motherboard 12 from a plurality of nozzles 27 four times so as to form the filter element 3 in a predetermined thickness. By doing this, it is possible to prevent difference in the thickness in a plurality of the filter elements 3 and to equalize light transparency in planar manner. Thus, in an ejecting apparatus, a color filter can be formed in more common way at low cost and more efficiently. Also, it is possible to provide an ejecting apparatus which can equalize factors such as electrooptical characteristics of the electrooptical members, color displaying characteristics by the liquid crystal apparatuses, and illuminating characteristics by an EL surface.
