Display panel and display device

A display panel, comprising:

• a substrate, comprising a display area, a peripheral area and a welding area, wherein the peripheral area surrounds the display area, and the welding area is positioned on a side of the peripheral area away from the display area;
• at least one barrier disposed on the substrate, the barrier being located in the peripheral area and surrounding the display area, the barrier comprising a single-sided barrier structure located between the display area and the welding area;
• an organic insulating structure arranged on the substrate, a portion of the organic insulating structure is located in the display area, another portion of the organic insulating structure is located in the peripheral area, the organic insulating structure is provided with a bottom surface facing the substrate, a top surface opposite to the bottom surface, and a first side surface which is coupled between the bottom surface and the top surface and faces the single-side barrier structure, the first side surface is a slope surface, and a slope angle of the slope surface ranges from 0° to 400;
• a touch electrode pattern arranged on a side of the organic insulating structure away from the substrate;
• a touch signal line arranged on a side of the organic insulating structure away from the substrate, a terminal of the touch signal line is electrically coupled to the touch electrode pattern, another terminal of the touch signal line is coupled to the welding area, and an orthographic projection of a portion, in the peripheral area, of the touch signal line on the substrate passes through an orthographic projection of the slope surface on the substrate.

• at least one barrier disposed on the substrate, the barrier being located in the peripheral area and surrounding the display area, the barrier comprising a single-sided barrier structure located between the display area and the welding area;
• an organic insulating structure disposed on the substrate, the organic insulating structure comprising a plurality of sub-insulating structures arranged in a stacked manner, a portion of each of the sub-insulating structures being located in the display area, each of the sub-insulating structures having a first boundary between the display area and the single-sided barrier structure, each of the sub-insulating structures except the sub-insulating structure farthest from the substrate comprising an extension;
• wherein, for any two adjacent ones of the sub-insulating structures, the extension of the sub-insulating structure proximal to the substrate is positioned between the first boundary of the sub-insulating structure away from the substrate and the single-side barrier structure;
• a touch electrode pattern arranged on a side of the organic insulating structure away from the substrate;
• a touch signal line arranged on a side of the organic insulating structure away from the substrate, a terminal of the touch signal line is electrically coupled to the touch electrode pattern, another terminal of the touch signal line is coupled to the welding area, and an orthographic projection of a portion, in the peripheral area, of the touch signal line on the substrate overlaps with an orthographic projection of the extension of each of the sub-insulating structures on the substrate;
• the sub-insulating structure with the extension is formed by patterning an organic material layer by using a two-tone mask plate, wherein, during a process of patterning, an area where the extension is to be formed corresponds to a semi-light-transmitting area of the two-tone mask plate.
