Abstract
Provided are a fine-particulate organic semiconductor material, a thin organic semiconductor film and an organic transistor. The fine-particulate organic semiconductor material is in a form of fine particles and is usable as an organic semiconductor material. The fine particles are fine thermotropic liquid crystal particles that undergo a phase transition into a liquid crystal state when heated to a temperature of from 50° C. to 350° C. The fine-particulate organic semiconductor material can easily and uniformly form the thin organic semiconductor film over a large area by a film printing process or a dispersion coating process. The thin organic semiconductor film has high electron mobility and high ON/OFF value.
