  • Active substrate, display apparatus and method for producing display apparatus
    Patent number: 7436477
    Abstract: An active substrate is provided, which comprises a switching element comprising a first drive region and a second drive region, a signal line being connected to the first drive region, a pixel electrode connected to the second drive region, a first layer comprising at least one of a semiconductor material and a conductive material, and connected to the pixel electrode, a second layer comprising at least one of a semiconductor material and a conductive material, and connected to the signal line; and an insulating film provided between the first layer and the second layer. At least a portion of the first layer and at least a portion of the second layer overlap each other so that the first layer and the second layer are short-circuited by applying first energy to the insulating film.
    Type: Grant
    Filed: September 17, 2004
    Date of Patent: October 14, 2008
    Assignee: Sharp Kabushiki Kaisha
    Inventors: Mutsumi Nakajima, Ichirou Shiraki, Osamu Sasaki, Hironobu Tatsumi, Hirofumi Katsuse, Masayuki Inoue, Hideo Kasugai, Keisuke Yoshida
  • Active matrix substrate, display apparatus, and method for producing the same
    Patent number: 7242442
    Abstract: In an active matrix substrate for allowing a point defect of a defect pixel portion, among a plurality of pixel portions arranged two-dimensionally, to be repaired by radiation of energy, the active matrix substrate includes one of a first protection member for absorbing excessive energy power and preventing pieces of a conductive material from being scattered; and a second protection member for preventing pieces of a conductive material from being scattered and for preventing a conductive layer from bulging. One of the first protection member and the second protection member is provided above at least one energy radiation portion.
