1. A display panel, having a plurality of pixel areas and a peripheral area surrounding the pixel areas, the display panel comprising:
a substrate, having a first substrate edge on a side along a first direction;
at least two planarization layers, disposed on the substrate;
a plurality of pads, disposed on the at least two planarization layers, and located in the pixel areas, wherein the pads comprise at least one first edge pad closest to the first substrate edge;
a first dummy pattern, disposed on the at least two planarization layers, and extending in the peripheral area between the at least one first edge pad and the first substrate edge; and
a plurality of light-emitting devices, electrically connected to the pads, wherein a space between the at least one first edge pad and the first substrate edge along the first direction is between 0 μm and 200 μm.
