  • Patent number: 9229570
    Abstract: A display device includes a first substrate, a display section that is on the first substrate and that displays an image, first pad portions at a first directional edge of the first substrate and connected to the display section and to a driver integrated circuit (driver IC) that supplies a driving voltage, a second substrate on the first substrate with the display section interposed therebetween, and which exposes the first pad portions, a touch section that is on the second substrate and that corresponds to the display section, second pad portions on the second substrate and connected to edges of the touch section, a main flexible printed circuit board (main FPCB) connected to the first pad portions, and a touch flexible printed circuit board (touch FPCB) connected to the second pad portions and overlapping the main FPCB.

  • Publication number: 20140355226
    Abstract: An anisotropic conductive film laminate is provided. The anisotropic conductive film laminate includes a first non-conductive film, an anisotropic conductive film disposed on the first non-conductive film, and a second non-conductive film disposed on the anisotropic conductive film, wherein the first non-conductive film has a higher viscosity than the second non-conductive film, and a lower viscosity than the anisotropic conductive film.

  • Patent number: 7001817
    Abstract: A method for fabricating a semiconductor device, including forming a gate insulating film and a gate electrode film on a semiconductor substrate, and patterning the gate electrode film to form a gate electrode. A portion of the gate insulating film is removed to form an undercut region beneath the gate electrode. A buffer silicon film is formed over an entire surface of the resultant substrate to cover the gate electrode and to fill the undercut region. The buffer silicon film is selectively oxidized to form a buffer silicon oxide film.
