1. A sensor-embedded display panel, comprising:
a substrate;
a light emitting element on the substrate, the light emitting element including a light emitting layer; and
a light absorption sensor on the substrate, the light absorption sensor including a light absorbing layer arranged in parallel with the light emitting layer along an in-plane direction of the substrate such that the light absorbing layer and the light emitting layer at least partially overlap in the in-plane direction,
wherein the light absorbing layer is configured to absorb light of a red wavelength spectrum, a green wavelength spectrum, a blue wavelength spectrum, an infrared wavelength spectrum, or any combination thereof,
wherein the light emitting layer includes a first organic material,
wherein the light absorbing layer includes a second organic material, and
wherein a difference between a sublimation temperature of the first organic material and a sublimation temperature of the second organic material is less than or equal to about 150° C., wherein each sublimation temperature of each given organic material is a temperature at which a weight reduction of 10% relative to an initial weight of the given organic material occurs during thermogravimetric analysis under an ambient pressure of about 10 Pa or less.
