Abstract: A display panel, in which a main display area, and a component area including a plurality of pixel groups and a transmission area are defined, includes a substrate, an inorganic insulating layer disposed on the substrate, where a first hole is defined through the inorganic insulating layer to correspond to the transmission area, a plurality of main display elements disposed on the inorganic insulating layer in the main display area, and a plurality of auxiliary display elements disposed on the inorganic insulating layer and corresponding to the pixel groups, respectively. The substrate includes a first base layer, a first barrier layer, a second base layer, a compensation layer, and a second barrier layer, which are stacked one on another, 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.
