Liquid crystal display device

摘要

A liquid crystal display device includes a TFT substrate having a display region with first and second electrodes, TFTs, scanning signal lines connected to the TFTs, a counter substrate, a liquid crystal layer sandwiched between the TFT and counter substrates, and sealed by a sealant, scanning line leads connected to the scanning signal lines and formed outside of the display region, video signal line leads connected to the video signal lines and formed outside of the display region and a shield electrode formed on the TFT substrate covering the scanning line leads but not the video signal line leads. The second electrode is connected to one of the 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.
