  • Display substrate and method of manufacturing the same
    Patent number: 8835956
    Abstract: A display substrate includes a substrate, a pixel part, a pad part and a sacrificial electrode. The substrate includes a display area and a peripheral area. The pixel part is on the display area and includes a switching element, and a pixel electrode electrically connected to the switching element. The pad part is on the peripheral area and contacts a terminal of an external device. The pad part includes a pad electrode a contact electrode. The pad electrode includes a first metal layer, and a second metal layer on the first metal layer, and the contact electrode contacts the second metal layer. The sacrificial electrode is spaced apart from the pad electrode and contacts the contact electrode. An exposed portion of the sacrificial electrode is exposed to an external side of the display substrate.

  • Display device with floating bar
    Patent number: 8411001
    Abstract: A display device includes a plurality of pixels, a data line transmitting a data voltage to the pixels, and a floating bar crossing the data line and being divided into a plurality of pieces. By dividing the floating bar into a plurality of pieces, a delay of a data signal can be prevented so that excellent images can be displayed. Furthermore, by disposing a diode between the pieces of the floating bar, an effect of dispersing static electricity can be maximized.
