The 3-3-1 model with neutral leptons contains four CP-even Higgs bosons when some constraints are imposed on the Higgs potential. Two Higgs bosons of this type are identified with the corresponding ones in the Two-Higgs-Doublet model (2HDM), an other being more massive does not couple with similar particles contained in the Standard Model (SM). The remaining particle is assumed to have no lepton-flavor-violating couplings. The contributions at one-loop order to \mathrmΓ(H→ lilj)(H ≡ h01,h02,h03) come mainly from neutral leptons leading them to depend very strongly on mass of charged Higgs boson, masses and the mixing matrix (VLab) of the neutral leptons. The numerical investigated results of \mathrmΓ(H→ lilj) in the spatial regions satisfying the experimental limit of lepton-flavor-violating decays of charged leptons (cLFV) indicate that the signal of SM-like Higgs boson (\mathrmΓ(h01→ lilj)) approaches the upper bound of the experimental limit and \mathrmΓ(H→ lilj) can take large values in the case of VLab = ULab(π/4,π/4,-π/4) and smaller in the case of VLab = ULab(π/4,0,0). Further, some distinct properties of \mathrmΓ(h02→ lilj) and \mathrmΓ(h03→ lilj) are also discussed.
