A display panel is divided into a first region and a second region located outside the first region, and includes a first sub-pixel, a second sub-pixel, a plurality of scan lines, a first common line, a second common line, and a black matrix. In the first sub-pixel, a first distance exists between the first common line and a neighboring scan line along a second direction. In the second sub-pixel, a second distance exists between the second common line and a neighboring scan line along the second direction, and the first distance is not equal to the second distance. The black matrix has a plurality of holes, including a first hole and a second hole. The first hole exposes the first sub-pixel and the first common line located in the first region. The second hole exposes the second sub-pixel and the second common line located in the second region.
