We study the Mott transition, antiferromagnetism, and superconductivity in layered organic conductors using the cellular dynamical mean-field theory for the frustrated Hubbard model. A $d$-wave superconducting phase appears between an antiferromagnetic insulator and a metal for ${t}^{\ensuremath{'}}/t=0.3--0.7$ or between a nonmagnetic Mott insulator (spin liquid) and a metal for ${t}^{\ensuremath{'}}/t\ensuremath{\ge}0.8$, …
