  The current atmospheric and solar neutrino experimental data favors the
bi-maximal mixing solution of the Zee-type neutrino mass matrix in which
neutrino masses are generated radiatively. This model requires the existence of
a weak singlet charged Higgs boson. While low energy data are unlikely to
further constrain the parameters of this model, the direct search of charged
Higgs production at the CERN LEP experiments can provide useful information on
this mechanism of neutrino mass generation by analyzing their data with
electrons and/or muons (in contrast to taus or charms) in the final state with
missing transverse energies. We also discuss the difference in the production
rates of a weak singlet from a weak doublet charged Higgs boson pairs at LEP.
