Abstract
In a display device and a method for inspecting the display device, precharge circuits are arranged on both sides of gate lines. Precharge circuits are arranged on both sides of data lines. A common electrode inspection circuit is connected to a common electrode. An inspection data processing circuit is arranged at one end of the gate lines. An inspection data processing circuit is arranged at one end of the data lines. In a first period, a first voltage is supplied to some of the gate lines, the data lines, and the common electrode. In a second period, a second voltage is supplied to some of the gate lines, the data lines, and the common electrode. The inspection data processing circuits acquire the voltage levels of the gate lines and the data lines based on the supply of the second voltage.
