An electrostatic discharge protection circuit, a display substrate and a display apparatus are disclosed. The electrostatic discharge protection circuit includes: a first conductive portion, having an end portion; and at least one electrostatic discharge portion, arranged on a same layer as the first conductive portion and spaced from the end portion of the first conductive portion, the at least one electrostatic discharge portion being configured to discharge electrostatic charges generated at the end portion of the first conductive portion. The electrostatic discharge portion is positioned near the end portion of the first conductive portion, and the electrostatic charges accumulated at the end portion can be discharged by the electrostatic discharge portion, and thus, the electrostatic discharge portion can share a breakdown current so as to prevent static electricity from entering other effective circuits.
