Abstract: Provided is an optical fingerprint recognition sensor. The optical fingerprint recognition sensor includes a transparent light emitting unit configured to emit light to a fingerprint, a light receiving unit disposed below the light emitting unit to vertically overlap the light emitting unit and configured to receive light reflected by the fingerprint, and a control unit disposed below the light emitting unit to vertically overlap the light emitting unit and configured to control the light emitting unit and the light receiving unit. The light emitting unit includes an organic layer.
