Abstract: A display panel and a display device are provided. The display panel includes a regular display region and an irregular display region. The display panel also includes a first substrate and a second substrate that are disposed opposite to each other, a liquid crystal layer disposed between the first and second substrates, and a heating electrode layer stacked with the liquid crystal layer. In the irregular display region, the heating electrode layer includes a plurality of first heating wires, and each first heating wire is connected between a first electrode wire and a second electrode wire. At least one first heating wire serves as a target heating wire including a first sub-segment and a second sub-segment. The first sub-segment has a resistance per unit length smaller than the second sub-segment, and the first sub-segment is closer to the regular display region than the second sub-segment.

Abstract: Provided are a display panel and a spliced display device. The display panel includes pixel rows and spacing areas. The pixel rows include a type-A pixel row adjacent to a first panel edge and type-B pixel rows including a first type-B pixel row. The spacing areas correspond to and are adjacent to the type-B pixel rows, and close to the first panel edge. The pixel row includes light-emitting devices and pixel circuits. The pixel circuit includes a first part and a second part. In the type-A pixel row, the first part is located at a side of the light-emitting device close to the first panel edge, and the second part is located in the spacing area corresponding to the first type-B pixel row. In at least one type-B pixel row, the pixel circuit is located at a side of the light-emitting device close to the first panel edge.
