Display panel and display device

The invention provides a display panel and a display device. The display panel comprises a substrate; the gate layer comprises a gate; a semiconductor layer including a semiconductor pattern including a first sub-pattern and a second sub-pattern; the source and drain electrode layer comprises a first electrode, and the first electrode is respectively connected with the first sub-pattern and the second sub-pattern; between the first sub-pattern and the second sub-pattern, a size of at least a partial region of an overlapping portion of the gate and the semiconductor pattern is smaller than a size of the first electrode in a width direction of the first electrode. According to the display panel and the display device provided by the invention, the hollow structure is arranged on the grid electrode and/or the semiconductor pattern corresponding to the connecting region, so that the overlapping area of the grid electrode and the semiconductor pattern between the first thin film transistor and the second thin film
