The embodiment of the invention provides a foldable display panel and a
display device. The foldable display panel comprises a first non-folding region, a folding region, a second non-folding region,a plurality of grid
electrode lines, a plurality of
data lines, a plurality of first data lead pins, a plurality of second data lead pins, a plurality of first data
lead lines and a plurality of second data
lead lines, wherein the first non-folding region, the folding region and the second non-folding region are arranged in the first direction; the first data lead pins are positioned in the firstnon-folding region; the second data lead pins are positioned in the second non-folding region; the grid
electrode lines extend from the first non-folding region in the first direction, pass through the folding region and extend to the second non-folding region; the
data lines also comprise first
data lines and second data lines; the first data lines are electrically connected with the first data lead pins; the second data lines are electrically connected with the second data lead pins. The folding shaft of the foldable display panel is basically parallel to the data lines. The embodiment alsoprovides the foldable display panel and the
display device; the arrangement positions of the data lines and the grid
electrode lines are exchanged, so that the data lines cannot generate transverse bending; the data lead pins are only positioned in the non-bending region; the panel reliability is improved.
