  • Patent number: 8637879
    Abstract: A display substrate for a display device includes a substrate, a switching device, a gate line, a data line, a pixel electrode, a plurality of common electrodes. The switching device includes an active pattern, a gate insulation layer, a gate electrode, a source electrode and a drain electrode. The gate line is electrically connected to the source electrode, and the data line is electrically coupled to the gate electrode. The pixel electrode is electrically connected to the drain electrode, and the common electrodes are disposed on the pixel electrode. A coupling capacitance among the common electrodes and the data line can be prevented and/or reduced to prevent a signal delay of the data line. Further, an aperture ratio of the display substrate can be improved by changing a layout of the data line and the gate line.

  • Publication number: 20080114110
    Abstract: An antistatic composition, a transfer roller manufactured by using the antistatic composition, and a method of manufacturing the same are provided. The antistatic composition includes about 0.05 to about 5 parts by weight of an antistatic agent including a metal salt compound, about 10 to about 50 parts by weight of a thermoplastic elastomer, and about 100 parts by weight of a base resin. The antistatic agent includes the metal salt compound and an ether compound. The metal salt compound includes an alkali metal salt compound.
