A display device comprising a display panel including a first non-folding area having a first emission area, a second non-folding area having a sensing area and a folding area that is disposed between the first non-folding area and the second non-folding area. A first light emitting diode is disposed in the first emission area and a second light emitting diode and a light receiving element are disposed in the sensing area. A processor obtains a biometric signal of a user by using the light receiving element and at least one of the first light emitting diode and the second light emitting diode. The processor generates biometric information based on the biometric signal. The processor detects the biometric signal when the display panel is folded so that the first non-folding area and the second non-folding areas are disposed to face each other.
