Title:
ELECTRODE FOR ORGANIC DEVICE AND ELECTRONIC DEVICE EMPLOYING SAME
Document Type and Number:
WIPO Patent Application WO/2005/020643
Kind Code:
A1
Abstract:
A carrier injection electrode layer (110) wherein a metal (112) for electron injection (namely a metal having a work function not more than 4.2 eV) and a metal (113) for hole injection (namely a metal having a work function larger than 4.2 eV) are blended into a single organic compound (111) is arranged between an organic layer (100) and a metal electrode (101) or between a first organic layer (100a) and a second organic layer (100b) in an organic device, so that the electron injecting function or the hole injecting function can be performed according to the polarity when a voltage is applied thereto, thereby enabling the organic device to have wider applications.
