Title:
ORGANIC ELECTROLUMINESCENCE ELEMENT
Document Type and Number:
WIPO Patent Application WO/2018/110244
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an organic EL element with excellent luminous efficiency. This organic EL element (1) is formed by laminating, on a transparent substrate (2), at least a first electrode (3) comprising a thin metal wire (3a) formed in a pattern and a transparent conductive layer (3b), an organic functional layer (4) and a second electrode (5); in a cross-section of the organic EL element (1) along the width direction of the thin metal wire (3a) and vertical with respect to the transparent substrate (2), defining M1 and M2 as the two ends of the portion of maximal thickness of the thin metal wire (3a) in the wire thickness direction, point E as the point where the vertical bisector of the line segment M1M2 intersects with the interface between the organic functional layer (4) and the second electrode (5), and the angle θ as the angle formed by a line segment M1E and the line segment M2E, the following conditional expression (1) is satisfied. 1.5 ≤ tan(θ/2) ≤ 10.0...
