  • Patent number: 7298435
    Abstract: A color filter 40 has a light-transmissive substrate 2, a reflecting layer 3 formed on the back substrate 2 and provided with openings 4, boundary layers 5 and 21 formed on the reflecting layer 3, and a plurality of coloring layers 6 enclosed by the boundary layers 5 and 21. A transparent coat layer 25 is provided between the reflecting layer 3 and the boundary layers 5 and 21. A step is formed between the openings 4 and the transparent coat layer 25. The coloring layers 6 are formed by applying the droplets 150 of colored fluid to the openings 4 first, and then to the transparent coat layer 25. The difference in color saturation of the color filter 40 in a reflective display mode and a transmissive display mode is reduced. Also, a liquid material is appropriately applied to the color filter 40, to enhance color balance.

  • Publication number: 20060250077
    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.

  • Publication number: 20060216617
    Abstract: The color filter of the present invention comprises ink films colored by ink drops 140 inside openings 111 enclosed by banks 112 demarcated and formed on a substrate 110. The banks 112 have a laminar structure comprising a metal film 120 and a photosensitive organic thin film 130 from the substrate 110 side. The inks should contain a solvent having a high boiling point. The bank layer may also be configured so that the peripheral edges of the bottom surface thereof are positioned inside from the peripheral edges of the light blocking layers, so that the light blocking layers have exposed surfaces on the upper surface thereof where the bank layer is not superimposed. Thus color filters can be provided which exhibit outstanding contrast without coloring irregularities.
