Disclosed are a display panel and a display device, the display panel including: a substrate including a display area, a peripheral area and a welding area; at least one barrier in the peripheral area and surrounding the display area, the barrier including a single-sided barrier structure between the display area and the welding area; an organic insulating structure including sub-insulating structures, each sub-insulating structure having a first boundary located between the display area and the single-sided barrier structure, for any two adjacent sub-insulating structures, the first boundary of the sub-insulating structure on a side away from the substrate being closer to the display area than the first boundary of the sub-insulating structure on a side proximal to the substrate; a distance between first boundaries of any two adjacent sub-insulating structures is greater than or equal to 20 μm; a touch electrode pattern; and a touch signal line.
