An object of the present invention is to provide an organic semiconductor material that easily provides a film having a high carrier mobility without the need for a complicated process. It was found that a BTBT derivative having a particular arylene acetylene structure is crystallized by way of a high-order liquid crystal phase having a highly ordered molecular arrangement, and thus the BTBT derivative easily forms a film having a high mobility without requiring complicated heat treatment even when the film is formed by printing. This finding led to the achievement of the object.
