We discuss that in the Minimal Supersymmetric Standard Model, the possibility for the lightest CP-even Higgs boson to be lighter than Z boson is not excluded by LEP2 data. The characteristic of the light Higgs boson scenario (LHS) is that the ZZh coupling and the decay branching ratio BR(h/A→bb) are simultaneously suppressed as a result of generic supersymmetric loop corrections. We show that the associate neutral and charged Higgs boson production process, pp → H^± h(A), can probe the LHS at the CERN Large Hadron Collider.
