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