  Left-Right twin Higgs(LRTH) model predicts the existence of a pair of charged
Higgs $\phi^{\pm}$. In this paper, we study the production of the charged Higgs
bosons pair $\phi^{\pm}$ via the process $e^{+}e^{-}\to \phi^{+}\phi^{-}$ at
the International Linear Collider(ILC). The numerical results show that the
production rates are at the level of several tens fb, this process can produce
the adequate distinct multi-jet final states and the SM background can be
efficiently reduced. We also discuss the charged Higgs boson pair production
via the process $q\bar{q}\to \phi^{+}\phi^{-}$ at the $CERN$ Large Hadron
Collider(LHC) and estimate there production rates. We find that, as long as the
charged Higgs bosons are not too heavy, they can be abundantly produced at the
LHC. The possible signatures of these new particles might be detected at the
ILC and LHC experiments.
