Abstract: A display panel and a display device are provided. The display panel includes a transistor, and the transistor includes an active layer extending in a second direction and a gate layer located on one side of the active layer. The gate layer includes a main stem portion extending in a first direction and a branch portion extending from a side of the main stem portion. In a top view, the active layer overlaps the main stem portion and the branch portion to realize a multiple gate design, optimize layout of the transistor, and facilitate increasing an aperture ratio of a pixel and realizing a sensing integration design.
