Abstract
A photoconductive composition and a display device adopting a photoconductive layer formed of the composition. The photoconductive composition includes an electron donor, an electron acceptor, a charge transmitting substance, a binder, a surfactant and a solvent, and the photoconductive composition is characterized in that a 1,4-diphenyl-1-butene-3-yne derivative is used as the electron donor. The photoconductive composition has excellent sensitivity and thermal decomposition property. Thus, there are scarcely residues left after the sintering process, thereby effectively preventing deterioration in image quality of a display device.
