Abstract
Display panel and display device are provided. The display panel includes a plurality of pixels and a blocking metal wire. The pixel includes a display unit and a control unit driving the display unit. The display unit at least includes a heating element and a phase change material layer. The heating element includes a first connecting terminal and a second connecting terminal. The control unit includes a first signal terminal and a second signal terminal. The control unit includes at least one diode, which includes a diode semiconductor layer including a first electrode contact region, a second electrode contact region and a connecting region. The blocking metal wire covers the connecting region and is insulated from the connecting region. The blocking metal wire is electrically connected to each of the first signal terminal and the first signal source or to each of the second connecting terminal and the second signal source.
