摘要：
A film-forming ink includes: film-forming materials containing a π-conjugated compounds; and a liquid medium which is capable of dissolving or dispersing the film-forming material and containing a compound represented by the following formula (I), wherein the compound is one in which the substituent of at least one of R1 to R6 is a linear or branched alkyl group, and the molecular structure of the one substituent is larger than the molecular structure of another substituent, and thus, the molecular weight of the whole molecule is biased towards the side where the one substituent is present.
