In this paper, we consider the viscous two-phase flow model with Navier-type slip boundary condition in a two-dimensional simply connected bounded domain with C-infinity boundary partial derivative Omega. By using new estimates of effective viscous flux on boundary integrals related to the Navier-type slip boundary condition, we establish the global existence and large time behavior of classical solutions to the two-phase flow model in time, provided that the initial energy is suitably small even if the density contains vacuum and has large oscillations. This is the first result concerning the global existence of classical solutions to the viscous two-phase flow model with density containing vacuum initially for general 2D bounded smooth domain.
