Abstract
A display panel which includes a display area and a peripheral area around the display area is provided. The peripheral area includes an electroluminescent layer test region, a TFT test region and a plurality of lead-out lines. The electroluminescent layer test region includes a plurality of thin film transistors having electroluminescent layers, a first test line connecting sources of the plurality of thin film transistors having electroluminescent layers, and a switch lead and a second test line connecting gates of the plurality of thin film transistors having electroluminescent layers. The TFT test region includes a plurality of thin film transistors. Each of the plurality of lead-out lines is used for connecting a source-drain metal layer of one thin film transistor in the electroluminescent layer test region and a source-drain metal layer of one thin film transistor in the TFT test region.
