In this study, we report the manifestation of geometric phases in the setup for quantum erasers. Our experiment includes a double-slit interferometer with the polarization as an internal state of a photon. With regard to the visibility of the interference fringe, we can demonstrate the disappearance of fringes by which-path marking and the recovery of interference using quantum erasers, and the phase shift of the fringe due to the evolution of the polarization state is attributed to the geometric phase or the Pancharatnam phase. For a certain arrangement, the geometric phase can be very sensitive to a change in state and this is observed as a rapid displacement of the fringes.
