Abstract
A TFT array substrate, a display panel and a display device are disclosed. The TFT array substrate includes a substrate, a display area and a peripheral area surrounding the display area. The display area and the peripheral area are arranged above the substrate. The peripheral area comprises a signal line and a shielding layer arranged above the signal line, and the shielding layer covers the signal line to shield EMI caused by a signal on the signal line. The TFT array substrate, the display panel and the display device can protect the display panel against EMI caused by the signal on the signal lines in the peripheral area, thereby improving stability and reliability of the TFT array substrate, the display panel and the display device, and enhancing sensitivity of a cellphone having the display panel.
