SUBSTRATE FOR ORGANIC ELECTRONIC DEVICE

摘要

PURPOSE: A substrate for an organic electronic device is provided to prevent interlayer delamination by effectively relieving a stress generated in a scattering layer and a high refractive layer. CONSTITUTION: A scattering layer (102) is formed on a base material layer (101). An elastic layer (103) is formed between the scattering layer and the base material layer or on the scattering layer. The average thickness of the elastic layer is 10 nm or more. The high refractive layer is formed on the scattering layer or the elastic layer. The refractive index of the high refractive layer for a beam of a wavelength of 550 nm is 1.8 to 3.5.
