Title:
ORGANIC ELECTROLUMINESCENCE ELEMENT
Document Type and Number:
WIPO Patent Application WO/2008/001756
Kind Code:
A1
Abstract:
An organic electroluminescence element is provided with a first electrode including
a transparent electrode or a semi-transparent electrode; a second electrode
facing the first electrode; and at least one organic layer arranged between the
first electrode and the second electrode. The organic electroluminescence
element is composed of a frame-like first auxiliary electrode, which is arranged
on the surface of the first electrode and is electrically connected to the first
electrode, and a second auxiliary electrode, which is arranged inside the frame
of the first auxiliary electrode and is composed of a fine wire electrode electrically
connected to the first auxiliary electrode. The first auxiliary electrode
and the second auxiliary electrode are composed of a material having a resistivity
lower than that of the first electrode.
