The invention discloses an electrostatic protection circuit, which comprises a bleeding unit and a trigger unit, wherein the bleeding unit is connected to a signal end and performs energy bleeding onthe signal end according to a trigger signal; the trigger unit is used for providing the trigger signal, wherein the trigger unit comprises a first transistor; the first transistor is switched on under the coupling action of stray capacitance between a first end of the first transistor and a control terminal to provide a starting current; the first end of the first transistor is connected with thesignal end; when the first transistor is switched on, the trigger unit provides the trigger signal according to the starting current. A mask layer aiming at a high voltage capacitor can be omitted when carrying out device design, thereby reducing the number of masks, and further reducing the design cost of the circuit, and improving the design efficiency of the circuit.
