In this paper we present a comprehensive study of electronic structure of Zn_{0.5}V_{0.5}Se from the theoretical point of view. Partial and total density of states for spin-polarized antiferromagnetic phase of Zn_{0.5}V_{0.5}Se as well as schematic layouts of the bands have been obtained using the ab initio self-consistent semirelativistic linear muffin-tin orbital method.
