Abstract
Provided is an OLED display panel, the OLED display panel includes a touch layer, wherein the touch layer includes a via hole structure including: a first conductive layer, an interlayer insulating layer, and a second conductive layer that are sequentially arranged, wherein the interlayer insulating layer is provided with a via hole, the second conductive layer is overlapped with the first conductive layer by the via hole, and at least part of a surface, in contact with the second conductive layer, of the interlayer insulating layer is uneven; wherein the uneven surface has a roughness in a value range of 0.05d≤r≤0.19d, where r represents the roughness, and d represents a thickness of the interlayer insulating layer, the roughness of the uneven surface being a distance between a top of convex and a bottom of concave in the uneven surface.
