The invention discloses an array substrate, a display panel, and a display device, where at least one control capacitor is added to a pixel zone, and the control capacitor has a first electrode at a fixed potential, and a second electrode at the same potential as a node between two adjacent transistors, so that when an active gate scan signal is stopped from being loaded on a gate line, the potential of the second electrode of the control capacitor is controlled to be kept at the potential of data signal loaded on a data line, to thereby lower the difference in voltage between the source and the drain of a transistor associated with the second electrode of the control capacitor so as to keep the potential at a connection point of the transistor with a storage capacitor to be the potential of a data signal loaded on the data line.
