Resin Film Substrate for Organic Electroluminescence and Organic Electroluminescence Device

A resin film substrate for an organic electroluminescence device, comprising:

• a resin film;
• and
• at least one layer on the resin film, the at least one layer including a gas barrier layer,
• wherein an outermost layer on a gas barrier side of the resin film includes on a surface thereof a concavo-convex structure for diffracting or diffusing a light lay.

A resin film substrate for an organic electroluminescence device, comprising:

• a resin film;
• and
• at least one layer on the resin film, the at least one layer including a gas barrier layer,
• wherein an outermost layer on a gas barrier side of the resin film includes a layer for diffracting or diffusing a light lay.

A resin film substrate for an organic electroluminescence device, comprising:

• a resin film;
• at least one layer on the resin film;
• the at least one layer including a gas barrier layer, and
• a concavo-convex structure for diffracting or diffusing a light lay between an outermost layer of the gas barrier side of the resin film and an adjacent layer thereto,
• wherein the outermost layer of the gas barrier layer side of the resin film includes a layer whose refractive index is greater than or equal to 1.45 and less than or equal to 2.10.
