Abstract
The present invention provides a display panel and a display device. A conductive film layer of the display panel is electrically connected to a gate electrode of a thin film transistor (TFT) through a first via hole, and the conductive film layer at least partially overlaps a source/drain electrode of the TFT to form a first capacitor. A second capacitor is formed in an overlapping region between a source/drain electrode of the TFT and the gate electrode of the TFT. Accordingly, a boost capacitance value of the display panel is increased, and a driving circuit requires less space.
