The invention discloses a shifting register, a driving method of the shifting register, a grid integrated drive circuit and a display device. A noise reducing module is additionally arranged in the existing shifting register, under the control of effective pulse signals input by a signal input end, the noises of a signal output end are eliminated by utilizing a reference signal end; meanwhile, in the grid integrated drive circuit composed of a plurality of cascaded shifting registers provided by the embodiment of the invention, by utilizing the connecting relation between the noise reducing modules of the shifting registers of different levels and signal output ends, when the output of the signal output end of one shifting register is abnormal, the noises can be coupled to the noise reducing module of the shifting register adjacent to the abnormal shifting register, the noises are then coupled and released to the reference signal end through the noise reducing module and are finally eliminated, therefore, the noises of the signal output ends of the shifting registers of different levels are cancelled out, and meanwhile, while the denoising capacity of the shifting registers is improved, the stability of grid scanning signals output by the grid integrated drive circuit is improved.
