Abstract: A display substrate. The display substrate includes: a plurality of pixel units; a gate driving unit supplying a gate signal to the plurality of pixel units and including a plurality of shift register circuits which are dependently connected to each other; a vertical start line supplying a vertical start signal to the gate driving unit; and an electrostatic protection unit having two ends connected to different points of the vertical start line, the electrostatic protection unit including a plurality of back-to-back diodes connected in series with each other between the two ends. Each of the back-to-back diodes include a pair of diodes connected in parallel to each other in a bidirectional diode structure.
