Abstract
The present invention discloses a display panel and a display device. By adding a stress adjustment layer having a plurality of patterned structures spaced apart from each other, the stress neutral surface can be effectively adjusted, and the stress of the metal trace is reduced when it is bent, to avoid or mitigate excessive stress causing generation and expansion of cracks in the stress adjustment layer, thereby reducing the probability of breakage of the metal trace when the flexible display is bent, thus reducing the risk of failure of the metal trace.
