1. A display panel comprising:
a substrate including a main display area and a component area, wherein the component area comprises a plurality of pixel groups spaced apart from one another and a transmission area between the pixel groups;
an inorganic insulating layer disposed on the substrate, wherein a first hole is defined through the inorganic insulating layer to correspond to the transmission area; and
a plurality of main display elements disposed on the inorganic insulating layer in the main display area;
wherein the substrate comprises a first base layer, a first barrier layer, a second base layer, a compensation layer, and a second barrier layer,
the compensation layer is disposed between the second base layer and the second barrier layer, and
a refractive index of the compensation layer has a value between a refractive index of the second base layer and a refractive index of the second barrier layer.
