Description

technical field

[0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique

[0002] In the display device, the function of the gate driving circuit is to sequentially output the on-state voltage (ie, the scanning signal) of the TFT (Thin Film Transistor) device row by row, so as to scan multiple gate lines in the display panel row by row.

[0003] The above-mentioned gate driving circuit may adopt a GOA (Gate Driver on Array, GOA) circuit, that is, the gate driving circuit 01 is directly integrated into the array substrate of the display panel 001 . In this case, in some GOA circuits, multi-stage cascaded effective GOA units (also known as effective shift registers) and virtual GOA units (i.e. Dummy GOA units, also referred to as virtual shift registers) are included; Among them, the effective GOA unit is connected to the gate line located in the display area, and the Dummy GOA unit is...
