1. A display panel comprising:
a first display region in which first light-emitting diodes are located;
a second display region at least partially surrounded by the first display region and in which display element groups including second light-emitting diodes and a transmission region are located;
an upper insulating layer defining an emission region of each of the first light-emitting diodes and the second light-emitting diodes and including a tapered portion adjacent to the transmission region;
an electrode on the upper insulating layer and including an opening to correspond to the transmission region; and
a blocking metal layer under the upper insulating layer,
wherein, on a plane, a distance between an edge of the blocking metal layer and a point of the electrode bent at a tapered edge of the upper insulating layer is greater than a set distance defined by Equation 1:
Y=H×tan θ
where, Y refers to the set distance, H refers to a height from a lower surface of the blocking metal layer to a lower surface of the electrode bent at the tapered edge of the upper insulating layer, and θ refers to one of angles of 45 degrees or less.
