An organic light-emitting display panel and a display device are provided. The organic light-emitting display panel includes a bending axis, a bending region, a first non-bending region, a second non-bending region, and at least one set of touch traces. The bending axis extends in a first direction. The first non-bending region and the second non-bending region are respectively located at two opposite sides of the bending region in a second direction perpendicular to the first direction. The at least one set of touch traces includes a plurality of touch traces. In the bending region, the plurality of touch traces extends from the first non-bending region to the second non-bending region. In the bending region, an angle between each of the plurality of touch traces and the bending axis is not 90°.
