Title:
ORGANIC LIGHT EMITTING ELEMENT FOR DISPLAY AND METHOD FOR MANUFACTURING THE SAME
Document Type and Number:
Japanese Patent JP2010272547
Kind Code:
A
Abstract:

To provide an organic light emitting element for a display and a method for manufacturing the organic light emitting element.

The organic light-emitting element includes: a positive electrode layer; an emissive layer; a negative electrode including an electron injection layer and a conductive layer; and a negative electrode contact layer electrically connecting the negative electrode with an electrical system for driving a screen. The conductive layer of the negative electrode is in direct contact at least with a part of the negative electrode contact layer. The organic light-emitting element further includes a connection layer formed with a conductive material wherein the connecting layer is in direct contact not only with the negative electrode contact layer but also with the conductive layer of the negative electrode. Accordingly, contact resistance between the negative electrode and the negative electrode contact layer is reduced, so that an amount of power supplied to the organic light-emitting element and a display including the organic light-emitting element as a fundamental component can be reduced.
