The invention discloses a shifting register unit, a grid driving circuit and a display base plate, relates to the technical field of display, and aims to solve the problems that a relatively large space is occupied by the shifting register unit and frame narrowing development is prevented as a capacitor in an energy storage module in the shifting register unit is relatively large. The shifting register unit comprises an input module, a reset module, an output module and a capacitor as an energy storage module, wherein the input module, the reset module and the output module are all positioned in a non-display area of the display base plate; the capacitor is positioned in a display area of the display base plate; the capacitor comprises a first electrode and a second electrode; the first electrode is a grid line positioned in the display area of an array base plate; the second electrode is an electrode lead opposite to the first electrode; the electrode lead is connected with a pull-up node in the shifting register unit through a connecting lead. The shifting register unit disclosed by the invention is used for displaying a driving signal provided by the base plate.
