Patent ID: 7709830

Claim:
An organic semiconductor device comprising at least a substrate, a gate electrode, a gate-insulating layer, an organic semiconductor layer in a crystallized crystal state, a drain electrode, and a source electrode, wherein the organic semiconductor layer is formed from an organic semiconductor material comprising a liquid crystal molecule, and exhibits a phase having periodic regularity at a location of a center of gravity in between the liquid crystal molecules, and the liquid crystalline organic semiconductor material has properties capable of exhibiting a supercooled state during a phase transition process, in which a phase having no periodic regularity at a location of a center of gravity in between the liquid crystal molecules is capable of being transferred into a phase having periodic regularity at a location of a center of gravity in between the liquid crystal molecules, and also, the phase of the material is capable of being transferred from said supercooled state to the phase having periodic regularity at a location of a center of gravity in between the liquid crystal molecules, and wherein the phase having no periodic regularity at a location of a center of gravity in between the liquid crystal molecules is a nematic liquid crystal phase and the phase having periodic regularity at a location of a center of gravity in between the liquid crystal molecules is a crystal phase.
