  • Patent number: 6744484
    Abstract: A liquid crystal apparatus with leak current preventing function includes first and second transparent substrates provided opposite to each other; first and second drive electrodes for an image, each formed on an opposite inner surface of the first and second transparent substrates; a sealing member (56) provided between the first and second transparent substrates for providing a liquid crystal injecting area and forming a gap in order to seal the liquid crystal therebetween; a plurality of conductive particles included dispersedly within the sealing member (56); a non-pixel electrode formed on position covered by the sealing member between the first and second transparent substrates; a dummy electrode (40D) formed opposite to the non-pixel electrode at the position in which the first and second transparent substrates are covered by the sealing member; and a conductive light-cutting film provided to at least one of inner surface of the first and second transparent substrates for cutting off unnecessary light

  • Patent number: 6741298
    Abstract: An LCD monitor for a computer includes an LCD module, a front frame and a rear main frame, where the front frame has a vertical flange portion corresponding to sides of the LCD module. A bracket is provided and has a vertical coupling portion for coupling to the flange of the front frame. A monitor case is provided for encasing the LCD module. A horizontal coupling portion is provided for coupling to the rear main frame such that the front frame, rear main frame and the monitor case are all coupled together using a novel side-mounting technique.

  • Patent number: 6697139
    Abstract: For preventing corrosion of signal lines (conductive layers for supplying signals to pixel areas) which are formed over one of a pair of substrates of a liquid crystal display device and are disposed so as to extend from the inside of an area surrounded by a sealing material toward the outside of the area, that at least one of the signal lines is covered with stacked layers formed of a first insulating film, a semiconductor layer, and a second insulating film formed sequentially over the at least one of the signal lines in this order.

  • Patent number: 6028654
    Abstract: ITO transparent electrodes having a low surface resistivity of 20-70 .OMEGA./.quadrature. are formed on a glass substrate. An additional ITO transparent electrode having a high surface resistivity of about 1 M.OMEGA./.quadrature. is formed so as to cover the low-resistivity transparent electrodes. Locally generated high-voltage static electricity is distributed in the high-resistivity transparent electrode, to prevent a spark between adjacent low-resistivity electrodes.

  • Patent number: 5963285
    Abstract: A method for manufacturing a liquid crystal display device includes the steps of forming a switching element having an electrode on substrate, forming an organic layer over the substrate and the switching element, forming an ion doped layer by doping ions selected from a group consisting of Si, P, Ge, B, As, Ba, Ti, Tb, and Bi into the organic layer, forming a contact hole in the ion doped layer exposing a portion of the electrode, and forming an inorganic layer connected to the electrode through the contact hole on the ion doped layer.
