Abstract: An embodiment is provided a display panel. The display panel includes a substrate, a light-emitting layer layer, an insulating layer, and a flat layer. The insulating layer includes a plurality of protruding portions and and adjacent to grooves between the protruding portions. A first side wall curve by a side wall of each of the protruding portions comprises a first arc line and a second arc line. A center point of the first arc line and a center point of the second arc line are respectively located on one side of the side wall that is biased toward each of the protruding portions and one side that is biased toward each of the grooves.
