The rescattering contribution to the inclusive and exclusive deuteron electro-disintegration at the values of the Bjorken scaling variable x=1, as well as in the so called \it cumulative region (x>1) is calculated within a relativistic approach based on the Feynman diagram formalism taking into account colour transparency effects by the inclusion of the \it finite formation time (FFT) of the ejected nucleon via the introduction of the dependence of the scattering amplitude of the ejectile upon its virtuality. In the cumulative region the FFT effects which result from the real part of the ejectile propagator are taken into account. It is found that the relative weight of the rescattering steadily grows with x becoming of the order of unity at x>1.4÷1.5. At such values of x the finite formation time effects become fairly visible, which may serve for their study at relatively small value of the four-momentum transferQ2. The relativistic rescattering contribution is compared with the Glauber rescattering, which is shown to be not valid in the cumulative region starting from x>1.4.
