The embodiment of the invention provides a shifting registering unit, a gate driving device, a display panel and a display device. The shifting registering unit, the gate driving device, the display panel and the display device are used for solving the problem that during standby unattended time, high nose exists in a signal output by an existing shifting registering unit when a clock signal is on a high level. According to the shifting registering unit, during standby unattended time, a frame of image is displayed, during all time periods except the time period when a scanning and triggering signal is on a high level and the time period when the output end of the shifting registering unit is on a high level, the output end of the shifting registering unit can be connected with a low-level signal end through a first downward-pulling driving module under the conditions that the received clock signal is on a high level or on a low level and the output end of the shifting registering unit is on a low level, so that noise coupled to the output end of the shifting registering unit from the high-level signal is released to the low-level signal end, and thus noise in a signal output by the shifting registering unit during standby unattended time is lowered.
