Abstract
The purpose of the present invention is to provide an organic semiconductor material having liquid crystallinity and high electron mobility. The present invention is an organic semiconductor material having at least a charge-transporting molecular unit (A) having a structure of an aromatic fused ring system and a cyclic structural unit (B) bonded to the aforementioned unit via a single bond, wherein the unit (A) and/or the unit (B) has a side chain composed of a unit (C), and wherein the organic semiconductor material exhibits a liquid crystal phase that is different from an N-phase, an SmA-phase or an SmC-phase.
