The unification of the early and late-time universe on the basis of the holographic principle taking into account the properties of the viscosity of the fluid in the spatial Friedman–Lemeter–Robertson–Walker metric is considered. In the description, the idea of generalized holographic dark energy cut-off proposed by Nojiri and Odintsov is used. To study the evolution of the unified Universe, a generalized equation of state of the dark fluid is used, including two asymptotic cases. As an example, a cosmological model with a constant thermodynamic parameter and a constant bulk viscosity is studied. Analytical expression for infrared radius in terms of the particle horizon and the energy conservation law are obtained from the holographic point of view. The viscous fluid describing the unification of the early and late-time Universe is represented as a generalized holographic energy.
