Abstract
Provided is a display panel, including a display pixel unit located in a display region, the display pixel unit including a threshold compensation transistor, the threshold compensation transistor including a first channel and a second channel being connected by a conductive connection portion; a dummy pixel unit located in a dummy region; a first signal line located in the dummy region and configured to provide a constant voltage; and a first conductive block connected to the first signal line. The display pixel unit includes a first display pixel unit, the first display pixel unit is a display pixel unit adjacent to the dummy pixel unit in a row direction, and in a plan view of the display panel, the first conductive block at least partially overlaps the conductive connection portion of the threshold compensation transistor of the first display pixel unit. A display device is further provided.
