  • Publication number: 20220310706
    Abstract: A display panel and a display device are provided. The display panel includes a main display region, a sub display region, a plurality of first pixel repeating units disposed in the main display region, and a plurality of second pixel repeating units disposed in the sub display region. A bend line boundary is firmed between the main display region and the sub display region. The bend line boundary includes a plurality of bending units. Each bending unit corresponds to at least one second pixel repeating unit, so that the pixel repeating units of the sub display region are consistent with the pixel repeating units at its edge, and a display difference is reduced.
