  • Apparatus and exposure mask having cylindrical bending prevention member for forming a liquid crystal fence
    Publication number: 20060268215
    Abstract: In a backlight assembly, an assembled substrate on which a spacer including a light-curable material is formed is disposed on a base body and a light supply unit disposed on the base body provides a light to the assembled substrate so as to cure the spacer. An exposure mask formed with an opening is positioned at a path through which the light is supplied so as to selectively supply the light to the spacer of the assembled substrate.
    Type: Application

  • Method of manufacturing LCD by dropping liquid crystals on a substrate and then pressing the substrates
    Patent number: 6011609
    Abstract: Liquid crystal displays are manufactured by dropping liquid crystals on at least one of a pair of liquid crystal display substrates and then placing the pair of liquid crystal display substrates adjacent one another, with the liquid crystals therebetween. The pair of liquid crystal display substrates is pressed toward one another, to thereby discharge excess liquid crystals from between the liquid crystal display substrates. The pair of liquid crystal substrates is then sealed to retain the liquid crystals therebetween. Accordingly, by not requiring the use of injection of liquid crystals, high vacuum processing is not required. Moreover, the number of processing steps can be reduced compared to conventional liquid crystal display manufacturing methods.
