Abstract
Provided is a complex biometric sensor. The complex biometric sensor includes a substrate including a light emitting region, a first light receiving region, and a second light receiving region, a light emitting part disposed adjacent to the substrate in the light emitting region, a color conversion layer disposed on the substrate in the light emitting region and vertically overlapping the light emitting part; a first light receiving layer disposed on the substrate in the first light receiving region, and a second light receiving layer disposed on the substrate in the second light receiving region. The light emitting part generates light of a first wavelength. The color conversion layer receives light of the first wavelength and emits the light of the first wavelength and light of the second wavelength. The first light receiving layer detects the light of the first wavelength. The second light receiving layer detects the light of the second wavelength.
