DISPLAY PANEL, MANUFACTURING METHOD THEREFOR, AND TFT TEST METHOD

摘要

A display panel, a manufacturing method therefor, and a thin film transistor (TFT) test method. The display panel comprises a display region (11) and a peripheral region (12) surrounding the display region. The peripheral region comprises: an electroluminescence layer test region (120), a TFT test region (121), and a plurality of pigtails (122). The electroluminescence layer test region (120) comprises a plurality of TFTs with electroluminescence layers (1201), first test lines (1202) connecting sources of the plurality of TFTs with electroluminescence layers (1201), and switch leads (1203) and second test lines (1204) connecting gates of the plurality of TFTs with electroluminescence layers. The TFT test region comprises a plurality of TFTs (1211). Each pigtail of the plurality of pigtails is used to connect a source and drain metal layer of one TFT in the electroluminescence layer test region and a source and drain metal layer of one TFT in the TFT test region.
