In view of pseudogap-like behavior found in organic layered superconductors κ-(BEDT-TTF)2X, we study the stability of correlated staggered flux state, which may bring about pseudogap behavior, with respect to the ordinary correlated Fermi sea as a low-lying normal state that underlies the unconventional superconductivity. To treat strong correlations, we apply a variational Monte Carlo method to a Hubbard model on a anisotropic triangular lattice, and construct a phase diagram of the normal state for large values of U/t. The results are qualitatively consistent with the features of non-doped κ-(BEDT-TTF)2 salts.
