  • Patent number: 7514187
    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.

  • Publication number: 20090053396
    Abstract: An object of the invention is to improve patterning accuracy while maintaining low cost, high throughput and a high degree of freedom of an optical material in a matrix type display device and a manufacturing method thereof. In order to achieve the object, a difference in height, a desired distribution of liquid repellency and affinity to liquid, or a desired potential distribution is formed by utilizing first bus lines in a passive matrix type display device or utilizing scanning lines, signal lines, common current supply lines, pixel electrodes, an interlevel insulation film, or a light shielding layer in an active matrix type display device. A liquid optical material is selectively coated at predetermined positions by utilizing the difference in height, the desired distribution of liquid repellency and affinity to liquid, or the desired potential distribution.

  • Patent number: 7481515
    Abstract: The invention makes uniform, in a plane, optical properties of optical members, such as the distribution properties of light transmission of a color filter, the color display properties of a liquid crystal device, and the light emission properties of an EL luminescent plane. During main scanning of color filter formation areas of a board in the X direction with an ink jet head having a nozzle row formed of a plurality of nozzles arranged in a row, a filter material is selectively discharged from the plurality of the nozzles to each of filer element areas arranged in a dot matrix to form filter elements, producing a color filter. First, the nozzle row is moved to positions “a” and “b” by main scanning in the X direction to enhance wettability of the surface of the areas and then main scanning is executed at each of the positions while successively moving the nozzle row to positions “c” through “k” by sub-scanning, thereby repeatedly discharging ink in the same portion of the areas.
