  • Patent number: 9454033
    Abstract: A liquid crystal display device sandwiching liquid crystal between a TFT substrate having a rectangular plane and an opposing substrate having a rectangular plane, wherein a long side of the TFT substrate is longer than a long side of the opposing substrate, the long side of the opposing substrate is formed with a chamfer, and a light shielding film made of metal is formed on the TFT substrate around a position corresponding to the center of the long side of the opposing substrate. By using the light shielding film, the chipping condition of the opposing substrate near the chamfer can be accurately and rapidly evaluated.
    Type: Grant

  • Patent number: 8586392
    Abstract: A manufacturing method of a display device including a gate electrode film, a first electrode film, a second electrode film, and a conductive film connected to the first electrode film and formed of a conductive layer including a first conductive layer and a second conductive layer formed overlapping the first conductive layer. The method includes the steps of forming the first electrode film and the second electrode film, forming the conductive layer such that the conductive layer is connected to the first electrode film and the second electrode film, and forming the conductive film by removing regions other than predetermined regions of the conductive layer, wherein the conductive layer forming step includes the steps of forming the first conductive layer on the respective upper surfaces of the first electrode film and the second electrode film and forming the second conductive layer on the upper surface of the first conductive layer.
