Shifting register unit, driving method thereof, grid driving circuit and display device

The embodiment of the invention provides a shifting register unit and a driving method thereof, a gate driving circuit and a display device, relates to the technical field of display, and aims to reduce the GOA size and facilitate a display panel to realize a narrow frame. The shifting register unit is characterized in that a first output sub-circuit transmits a clock signal of a clock signal endto a signal output end under the control of a pull-up node; the first second output sub-circuit in the N second output sub-circuits transmits the signal of the signal output end to the first output end under the control of the first signal end; the ith second output sub-circuit in the N second output sub-circuits is controlled by the ith signal end; wherein N is a positive integer larger than or equal to 2, i is larger than or equal to 2 and smaller than or equal to N, and i is a positive integer. 本发明实施例提供一种移位寄存器单元及其驱动方法、栅极驱动电路、显示装置，涉及显示技术领域，可减少GOA尺寸，便于显示面板实现窄边框。一种移位寄存器单元，包括：第一输出子电路在上拉节点的控制下，将时钟信号端的时钟信号传输至信号输出端；N个第二输出
