Document Type and Number:
Japanese Patent JP6155566
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a laminated substrate for an organic LED element, which has high light extraction efficiency.SOLUTION: A laminated substrate 11 includes a transparent substrate 20, an uneven layer 30 provided on the transparent substrate 20, and a flattening layer 40 provided on an uneven surface of the uneven layer 30 and is for extracting emitted light of an organic layer 60 from a surface on the side opposite to the uneven layer 30 side of the transparent substrate 20 to the outside through the flattening layer 40 and the uneven layer 30. The uneven layer 30 includes a base material 33 and a light scattering material 34 dispersed in the base material 33.
