RESIN FILM SUBSTRATE FOR ORGANIC ELECTROLUMINESCENCE AND ORGANIC ELECTROLUMINESCENCE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a low-cost resin film substrate for organic electroluminescence, including a gas barrier layer having high gas barrier properties while being improved in light extraction efficiency, and an organic electroluminescence device using the resin film substrate for organic electroluminescence.

SOLUTION: In a substrate for organic electroluminescence including at least one gas barrier layer on a resin film, a layer constituting the outermost surface on a side having the gas barrier layer is a high refractive index layer having a refractive index of 1.45 or more and 2.10 or less, and a layer adjacent to the high refractive index layer is a layer for diffracting or diffusing light.
