This application discloses a driving substrate and a display panel. In this embodiment, the output electrode is used to electrically connect to a light-emitting device. The active layer includes a semiconductor portion, a first conductive portion, and a second conductive portion. The first conductive portion is connected to the side of the semiconductor portion near the output electrode, and the second conductive portion is connected to the side of the semiconductor portion away from the output electrode. The first conductive portion is connected to the output electrode, and the surface resistivity of the first conductive portion is less than that of the second conductive portion. A gate is disposed overlapping the semiconductor portion. An input electrode is connected to the second conductive portion. The input electrode, output electrode, active layer, and gate are used to form a thin-film transistor. In this application embodiment, because the surface resistivity of the first conductive portion is less than that of the second conductive portion, the voltage drop of the active layer near the output electrode is reduced, thereby reducing the influence of hot carriers on the threshold voltage.
