The display panel includes a display region, and the display region includes a first group of pixels, a second group of pixels, a third group of pixels, a fourth group of pixels, a first scan line, a second scan line, a first signal line, and a second signal line. The first group of pixels include a first pixel and are arranged in a row direction. The second group of pixels include a second pixel and are arranged in the row direction. The third group of pixels include a first pixel and are arranged in a column direction that intersects the row direction. The fourth group of pixels include a second pixel and are arranged in the column direction. The first signal line is electrically connected to the third group of pixels and the second signal line is electrically connected to the fourth group of pixels. The first scan line is electrically connected to the first group of pixels and the second scan line is electrically connected to the second group of pixels.
