Abstract
A TFT array for a liquid crystal display device in which inferiority due to electrification or abnormal discharge during fabrication process can be decreased. The TFT array comprises TFTs for display each connected to a respective one of pixel electrodes disposed in a matrix, gate wirings, signal lines, a common conductor line on the gate wiring side, a common conductor line on the signal line side, nonlinear elements respectively disposed between the gate wirings and the common conductor line on the gate wiring side and between the signal lines and the common conductor line on the signal line side. A gate electrode of a TFT in each of the nonlinear elements is formed separately from the corresponding common conductor line and is electrically coupled thereto via contact holes and a third conductor layer. A source/drain electrode of a TFT in each of the nonlinear elements is formed seprately from the corresponding common conductor line and is electrically coupled thereto via contact holes and the third conductor layer.
