Display panel and display device

The utility model discloses a display panel and a display device. The display panel comprises a flexible display substrate and a polaroid. The edge of the flexible display substrate comprises a first straight edge and a first corner edge; every two adjacent first straight edges are connected through a first corner edge. The polaroid is located on the light emitting side of the flexible display substrate; the edge of the polaroid comprises a second straight edge and a second corner edge; every two adjacent second straight edges are connected through a second corner edge. One second corner edge corresponds to one first corner edge, the second corner edge and the corresponding first corner edge are located on the same side of the display panel, and the second corner edge shrinks inwards by a set distance relative to the first corner edge to the display area of the flexible display substrate. The problem that double folding areas of a four-curved-surface display screen are wrinkled can be solved.
