Abstract

The invention provides a display panel, a manufacturing method thereof and a display device, and relates to the technical field of display. According to the display panel, the resistance reduction wires are arranged on the substrate in the pixel interval area, the interlayer dielectric layer is arranged on the substrate, the interlayer dielectric layer is provided with the openings exposing the resistance reduction wires, the signal wires are arranged in the openings and connected with the resistance reduction wires, and the width of the openings is larger than or equal to that of the signal wires in the row direction of the display panel. The signal lines are formed in the openings of the interlayer dielectric layer, and the widths of the openings are greater than or equal to those of thesignal lines, that is, the signal lines are only located in the openings and do not exceed the surface of the interlayer dielectric layer, and therefore the segment difference of the display panel located in the pixel interval area is reduced; the thickness of the flat layer at each subsequently formed region is relatively uniform, and the planarization effect is relatively good, so that the riskthat the flat layer is peeled off due to the segment difference of the pixel interval regions is reduced, and the reliability of a product is improved.
