  • Patent number: 7369188
    Abstract: In a thin film transistor substrate, a method of manufacturing the same, and a display apparatus having the same, a thin film transistor, a gate member, and a storage member are formed on an insulating substrate. The gate member has a gate line and a gate electrode electrically connected to the gate line, and the storage member has a storage line, a first storage electrode, and a second storage electrode. A data member is formed on an active layer. The data member includes a data line crossing the gate line, a third storage electrode overlapped with the first storage electrode and a fourth storage electrode overlapped with the second storage electrode. Thus, a capacitance variation of a storage capacitor may be prevented, thereby improving display quality of a display apparatus.

  • Publication number: 20080001937
    Abstract: A display substrate includes a TFT layer, a passivation layer, an organic layer, an inorganic insulating layer and a pixel electrode. The TFT layer includes gate and data lines, a thin film transistor and a storage electrode. The data line crosses the gate line, and is electrically insulated from the gate line by a gate insulating layer. The TFT is electrically connected to the gate and data lines. The passivation layer covers the TFT layer. The organic layer is on the passivation layer. The inorganic insulating layer of a low temperature deposition is on the organic layer, and the low temperature is about 100° C. to about 250° C. The pixel electrode is on the inorganic insulating layer to be electrically connected to the TFT through a contact hole that is formed through the inorganic insulating layer, the organic layer and the passivation layer. The inorganic insulating layer helps to block leakage of impurities from the organic layer to layers above the inorganic insulating layer.
