Patent ID: 7884356

Claim:
A donor substrate for forming a nano conductive film, the donor substrate comprising: a base substrate; and a transferring layer disposed on the base substrate, the transferring layer comprising: nano conductive particles; and an organic semiconductor in which the nano conductive particles are dispersed, wherein the organic semiconductor is at least one compound selected from the group consisting of compounds represented by Formulae III through VII: wherein R 1 and R 2 are each independently an alkyl group having 1 to 40 carbons, a cycloalkyl group having 4 to 40 carbons, an alkoxy group having 1 to 40 carbons, an aryl group having 6 to 40 carbons, an aryloxy group having 6 to 40 carbons, an alkenyl group having 2 to 40 carbons, an alkylaryl group having 7 to 40 carbons, an arylalkyl group having 7 to 40 carbons, an arylalkenyl group having 8 to 40 carbons, or an alkynyl group having 2 to 40 carbons; R 3 and R 4 are each independently an alkyl group having 4 to 40 carbons, a silyl group having 3 to 40 carbons, or a siloxyl group having 3 to 40 carbons; R is a compound selected from the group consisting of pentacene of which N-sulfonyl group is substituted, and compounds represented by formulae IV through VI; and X 1 , X 2 , X 3 and X 4 are each independently hydrogen or a halogen atom, but are not all hydrogen atoms.
