SUBSTRATE FOR ELECTRONIC DEVICE, LAYERED BODY FOR ORGANIC LED ELEMENT, METHOD FOR MANUFACTURING THE SAME, ORGANIC LED ELEMENT, AND METHOD FOR MANUFACTURING THE SAME

摘要

An organic LED element having improved reliability in a long-term use, and having improved external extraction efficiency up to 80% of emitted light is provided. A substrate for an electronic device according to the present invention includes: a translucent substrate; a scattering layer including a glass and being provided on the translucent electrode; a coating layer provided on the scattering layer; and scattering materials that are present in the scattering layer and the coating layer and are not present on a surface of the coating layer, in which a surface of the coating layer has waviness in which a ratio Ra/Rλa of waviness height Ra to waviness period Rλa exceeds 1.0×10−4 and is 3.0×10−2 or less.
