20120300152Liquid Crystal Display Device - A liquid crystal display device includes a TFT substrate having a display region which has first and second electrodes, a plurality of TFTs and a plurality of scanning signal lines connected to the plurality of TFTs, a counter substrate, a liquid crystal layer sandwiched between the TFT and counter substrates, and sealed by a sealant, a plurality of scanning line leads connected to the plurality of scanning signal lines formed in a region outside of the display region, and a shield electrode formed on the TFT substrate covering the plurality of scanning line leads. The second electrode is connected to one of the plurality of TFTs, and liquid crystal molecules of the liquid crystal layer are driven by an electric field, which is generated between the first and second electrodes. The shield electrode is electrically connected to the first electrode and overlapped with the sealant in plan view.11-29-2012
20120300150DISPLAY DEVICE - A protective circuit includes a non-linear element which includes a gate electrode, a gate insulating layer covering the gate electrode, a first oxide semiconductor layer overlapping with the gate electrode over the gate insulating layer, and a first wiring layer and a second wiring layer whose end portions overlap with the gate electrode over the first oxide semiconductor layer and in which a conductive layer and a second oxide semiconductor layer are stacked. Over the gate insulating layer, oxide semiconductor layers with different properties are bonded to each other, whereby stable operation can be performed as compared with Schottky junction. Thus, the junction leakage can be reduced and the characteristics of the non-linear element can be improved.11-29-2012
