We have studied the relativistic effect on the spin state of a massive Dirac particle under an arbitrary Lorentz transformation using the Foldy-Woutheysen representation. We have obtained the transformation matrix from the state of a massive Dirac particle with an initial momentum to a state with a transformed momentum under an arbitrary homogeneous Lorentz transformation. We have shown moving observers obtain the consistent monotonic behavior between the concurrence and the maximum value of Bell parameter for the spin state of the pair of particles.
