Display panel and display device

A display panel, comprising:

• a base substrate comprising a display region and a non-display region surrounding the display region, wherein the non-display region comprises a bendable region and a bonding region disposed on a side, away from the display region, of the bendable region;
• a backplane trace layer disposed on the base substrate, comprising a first source-drain electrode layer, a first planarization layer, a second source-drain electrode layer, a second planarization layer, and a third source-drain electrode layer that are laminated;
• a package layer disposed on the backplane trace layer;
• a touch electrode layer disposed on the package layer, comprising a touch electrode disposed at least in the display region;
• and
• a touch trace electrically connected to the touch electrode, wherein the touch trace is disposed in the non-display region and extends through the bendable region to the bonding region, and the touch trace comprises a first trace portion, a second trace portion, and a third trace portion that are electrically connected, wherein the first trace portion spans the bendable region, the second trace portion is not overlapped with the bendable region, an orthographic projection of the third trace portion on the base substrate is at least partially overlapped with an orthographic projection of the first trace portion on the base substrate, the first trace portion is disposed in the second source-drain electrode layer, the second trace portion is disposed in the touch electrode layer, the third trace portion is disposed in the third source-drain electrode layer, and the first trace portion comprises a first sub-portion and a second sub-portion, the second planarization layer isolating the first sub-portion from the third trace portion, and the second sub-portion being electrically connected to the third trace portion by a misaligned via running through the second planarization layer.

A display device, comprising:
