  • Patent number: 8278723
    Abstract: A thin film transistor substrate capable of appropriately maintaining driving performance even when there is a difference between manufacturing processes and a method of manufacturing the same. The thin film transistor substrate includes: a gate electrode formed on an insulating substrate; a semiconductor layer formed on the gate electrode; and a plurality of thin film transistors each having a source electrode and a drain electrode that are formed on the gate electrode and the semiconductor layer so as to be spaced apart from each other. At least one of the plurality of thin film transistors is a dummy thin film transistor that does not have the semiconductor layer between the source electrode and the drain electrode.

  • Publication number: 20090219457
    Abstract: A display substrate includes a source pad part, a plurality of storage wirings and a first voltage wiring. The source pad part includes a first voltage input pad receiving a storage common voltage. The storage wirings transmit the storage common voltage to a plurality of pixels. The first voltage wiring is connected to the first voltage input pad to be extended in a direction crossing the storage wirings. The first voltage wiring includes a first protrusion part overlapping a first end portion of each of the storage wirings. Therefore, defects of the display substrate may be detected by an electrical test and then repaired, and test efficiency of the display substrate may be enhanced.
