Abstract
A gate driving circuit includes a shift register circuit and an auxiliary circuit which are disposed at different sides of a pixel array. The shift register circuit includes an (N−1)th shift register stage for generating an (N−1)th gate signal according to a first clock, an Nth shift register stage for generating an Nth gate signal according to a second clock, and an (N+1)th shift register stage for generating an (N+1)th gate signal according to a third clock. The auxiliary circuit includes a first transistor. The first transistor performs the signal voltage stabilization and level switching acceleration operations on the Nth gate signal according to the (N−1)th gate signal and the second clock.
