The most general scalar sector of the 3-3-1 model with three lepton singlets, where one scalar carrying lepton number 2 has a vacuum expectation value (VEV) $n_2$, is considered. We show that the new VEV $n_2$ leads to new constraint among Higgs self-coupling constants. The Higgs sector contains 6 massless fields: two in the charged sector, three in pseudoscalar sector and one/three in neutral scalar sector. This number is enough for massive gauge bosons.
