Abstract: A display panel and a display device are provided. The display panel is divided into a display region and a non-display region, wherein the display panel includes: a first blocking wall arranged in the non-display region and surrounding the display region; a bending part; and an electrostatic protection unit arranged in a part of the non-display region corresponding to the bending part and located on a side of the first blocking wall facing away from the display region. By the arrangement of the electrostatic protection unit, problems such as breakdown of the transistors due to electrostatic accumulation caused by bending operation of the display panel, as well as encapsulation structure failure due to damage to the first blocking wall can be avoided.
