The study of the electronic spectrum of the layered nanohybrid structure with a stage ordering reveals the effect of such ordering with an increase of lattice constant in the direction perpendicular to the layer on the electronic band structure of GaSe-type crystals. The analysis is performed for changes of the electronic spectrum and the density of electronic states in the layered crystals produced by the structure modulation due to the appearance of periodical blocks consisting of a small number of layers. A polymodal structure of the density of electronic states is studied numerically as well as its dependence on the number of layers in the block for stage ordered crystals of the GaSe-type.
