Patent ID: 7645812

Claim:
A composition for forming a buffer layer of a thin film transistor which is used to form a polyparaphenylenevinylene (PPV) compound represented by Formula 1: where R is a C1-C20 silyl group substituted with cyclohexyl or phenyl, m is an integer from 2 to 4, and n is an integer equal to or more than 1, the composition comprising: a photobase generator; a solvent; and a precursor represented by Formula 2: where R is a C1-C20 silyl group substituted with cyclohexyl or phenyl; m is an integer from 2 to 4; X is Cl, Br, or I; and n is an integer equal to or more than 1, wherein the amount of the solvent is in the range of 1 to 20 parts by weight based on 100 parts by weight of the precursor.
