  • Publication number: 20070019148
    Abstract: It is the object of the present invention to provide a method of producing a liquid crystal display by which spacer particles can be arranged efficiently, highly precisely and selectively in light shielded regions (non-display parts) or the regions corresponding to the light shielded regions of a substrate for a liquid crystal display by using an ink-jet apparatus and by which a liquid crystal display capable of displaying images with excellent display quality without occurrence of depolarizing attributed to the spacer particles or deterioration of contrasts and color tone owing to light blank can be realized.

  • Publication number: 20060109415
    Abstract: It is an object of the present invention to provide a method of fabricating a liquid crystal display, which can prevent degradation in liquid crystal display performance such as contrast due to the cohesion of spacers and fabricate a liquid crystal display of high image quality, having high resolution. The present invention relates to a method of fabricating a liquid crystal display, which has a step of ejecting spacer dispersion liquid obtainable by dispersing a spacer in a dispersion medium in a specific region of the surface of a substrate from a nozzle of an ink-jet system and locating the spacer in a specific region on the substrate, at least 80% by weight of the dispersion medium having a boiling point of 200° C.

  • Publication number: 20050128421
    Abstract: In accordance with the present invention, it is possible to provide the method for manufacturing a liquid crystal display, a substrate for liquid crystal display, a method for manufacturing the substrate for a liquid crystal display, and the dispersion of spacer particles, in which a spacer particle can be precisely located at an arbitrary position on a substrate by an ink-jet method. The present invention relates to a method for manufacturing a liquid crystal display, wherein spacer particles are located at an arbitrary position on a substrate by ejecting a dispersion of spacer particles by an ink-jet method, a diameter D1 of an adhered droplet of said dispersion of spacer particles, having adhered to said substrate, and a diameter D2 of the adhering spacer particles, remaining after the said dispersion of spacer particles is evaporated, satisfying a relationship of Equation (1). D2<(D1×0.
