Abstract
Array substrate, display panel and display device are provided. The array substrate includes multiple scanning lines, multiple data lines, multiple shift registers and multiple switching units. Each shift register is used for inputting a scanning signal to one terminal of a corresponding scanning line, the other terminal of each scanning line is connected with a first terminal of the switching unit, a second terminal of the switching unit receives a first reference voltage, a control terminal of the switching unit receives a first control signal. The shift register and the switching unit simultaneously pull down a voltage level of the scanning line to a low level. The present invention can realize a narrow frame, increase the user experience and ensure that the time that the voltage level of the scanning line pulled to the low level is the same.
