We investigate and elucidate the phase structure of QCD for general number of flavors NF with Wilson quarks, varying NF from 2 up to 300. Based on numerical results combined with the result of the perturbation theory we propose the following picture: When NF ≥ 17, there is only a trivial fixed point and therefore the theory in the continuum limit is trivial. On the other hand, when 16 ≥ NF ≥ 7, there is a non-trivial fixed point and therefore the theory is non-trivial with anomalous dimensions, however, without quark confinement. Theories which satisfy both quark confinement and spontaneous chiral symmetry breaking in the continuum limit exist only for NF ≤ 6. We also discuss the structure of the deconfining phase at finite temperatures for the small number of flavors such as NF=2 and 3, through a systematic study of it for general number of flavors.
