Embodiments of the present disclosure relate to a technique of liquid crystal display, and provide a shift register unit circuit, a shift register, an array substrate and a display apparatus. A first TFT is added in the shift register unit circuit and is used to pull down the level of a node PU when a frame start signal is at a high level and a forward clock signal changes from a low level to the high level, such that a H-line defect generated in an output signal caused by a coupling effect of a coupling circuit can be avoided, which is advantageous for increasing productivity and yield rate of products. |
