Abstract

The invention relates to a mold, a method for manufacturing an organic light emitting diode and the organic light emitting diode. The mold has a flat surface and a plurality of protrusions on the main surface, the average pitch of the plurality of protrusions is 50 nm to 5 μm, the average aspect ratio of the plurality of protrusions is 0.01 to 1, and among the plurality of protrusions More than 80% have a specific curved surface, and the specific curved surface deviates from the first point by only 1 / 10 of the average pitch by setting an arbitrary point on the specific curved surface as the first point When the point of is set as the second point, the inclination angle of the second tangent plane connected to the second point with respect to the first tangent plane connected to the first point is within 60°.

Description

technical field [0001] The invention relates to a mold, a method for manufacturing an organic light emitting diode and the organic light emitting diode. This application claims priority based on Japanese Patent Application No. 2015-178324 for which it applied in Japan on September 10, 2015, and uses the content here. Background technique [0002] Organic light-emitting diodes are light-emitting elements that utilize organic electroluminescence. An organic light emitting diode generally has a structure in which an anode and a cathode are respectively provided on both surfaces of an organic semiconductor layer including a light emitting layer containing an organic light emitting material. The organic semiconductor layer includes an electron injection layer, an electron transport layer, a hole transport layer, a hole injection layer, and the like as necessary, in addition to the light emitting layer. Organic light emitting diodes have advantages such as less viewing angle dep...
