Claim Text:
1. A dispersion for forming an organic semiconductor film, which is useful in forming the organic semiconductor film, the dispersion comprising: an organic solvent comprising an aprotic polar solvent having a specific inductive capacity of from 30-60; and a fine-particulate organic semiconductor material dispersed in the organic solvent, wherein 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., and the fine particles comprise a perylene tetracarboxylic diimide derivative, wherein the perylene tetracarboxylic diimide derivative is N,N′-ditridecyl perylene tetracarboxylic diimide represented by the following structural formula (1): or N,N′-bis(3-(n-dodecyloxy)-n-propyl)-3,4,9,10-perylene tetracarboxylic diimide represented by the following structural formula (2):
