摘要： An inspection circuit is constructed by first inspection TFTs provided to one end sides of signal lines, and second inspection TFTs provided to the other end sides of the signal lines. By using both the first inspection TFTs and the second inspection TFTs, the driving capability can be secured while miniaturizing the first inspection TFTs and the second inspection TFTs. Therefore, the signal lines can be reliably inspected while saving the space for the inspection circuit.

摘要翻译： 检测电路由设置在信号线的一端侧的第一检查用TFT构成，第二检查用TFT设置在信号线的另一端。 通过使用第一检查TFT和第二检查TFT两者，可以确保驱动能力，同时使第一检查TFT和第二检查TFT小型化。 因此，能够可靠地检查信号线，同时节省检查电路的空间。

摘要： A display device includes scanning lines disposed along rows of display pixels, signal lines disposed along columns of the display pixels, pixel switches disposed near intersections between the scanning lines and the signal lines, pixel electrodes connected to the pixel switches, a counter-electrode disposed to be opposed to the pixel electrodes, storage capacitance lines disposed substantially parallel to the scanning lines, first inspection switches connected to the scanning lines in a peripheral section, second inspection switches connected to the signal lines in the peripheral section, a first wiring line which supplies a signal for turning on/off the first inspection switches, a second wiring line which supplies a signal for turning on/off the second inspection switches, and a third wiring line which applies a signal to the counter-electrode and the storage capacitance lines.
