Shift register, gate driving circuit and display apparatus

Abstract

A shift register, a gate driving circuit and a display apparatus, belonging to the technical field of display. The shift register comprises: a first input sub-circuit (11), a second input sub-circuit (12), an output sub-circuit (3), at least one pull-down control sub-circuit (41 / 42), at least one pull-down sub-circuit (51 / 52), at least one first auxiliary sub-circuit and at least one second auxiliary sub-circuit; the pull-down control sub-circuits (41 / 42) are connected to the pull-down sub-circuits (51 / 52) on a one-to-one basis, the connection nodes being pull-down nodes; a connection node between the first input sub-circuit (11), the second input sub-circuit (12) and the output sub-circuit (3) is a pull-up node (PU); each first auxiliary sub-circuit is configured to, in response to a first input signal and by means of a second scanning signal, pull down the potential of a pull-down node corresponding thereto; each second auxiliary sub-circuit is configured to, in response to a second input signal and by means of a first scanning signal, pull down the potential of a pull-down node corresponding thereto.
