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.
