Abstract: The present disclosure discloses a shift register, a driving method thereof, a gate drive circuit, an array substrate and a display device. With a signal control circuit, a branch control circuit, a cascade signal output circuit and at least two scan signal output circuits, each shift register can output at least two scan signals to correspond to different gate lines in a display panel. This can reduce the number of shift registers in a gate drive circuit and the space occupied by the gate drive circuit and can achieve an ultra-narrow frame design, as compared with an existing shift register that can only output one scan signal. Moreover, as signals of different output control node do not influence each other, the output stability can also be improved.
