Title:
ORGANIC ELECTROLUMINESCENCE ELEMENT
Document Type and Number:
WIPO Patent Application WO/2012/161113
Kind Code:
A1
Abstract:
This organic electroluminescence element is provided with a substrate (10), a first electrode (20) disposed on a first surface (101) of the substrate (10), second electrodes (40) that face the first electrode (20) at the first surface (101) side, and a functional layer (30) that exists between the first and second electrodes (10, 40) and includes at least a light-emitting layer (32). The resistivities of the first and second electrodes (20, 40) are less than a predetermined resistivity corresponding to the resistivity of a transparent conductive oxide. The second electrodes (40) each have an opening (41) for extracting light from the functional layer (30). The element also includes a conductive layer (50) and insulating parts (21). The conductive layer (50) is optically transparent, is disposed on the openings, and is in contact with the second electrodes (40) and the functional layer (30). The insulating parts (21) are provided in the shape of the openings (41) between the first electrode (20) and the second electrodes (40).
