摘要：
There is provided an organic electroluminescence display includes a lower electrode formed on a substrate, a device separation film formed on the lower electrode, an organic compound layer formed on the device separation film and including a light emission layer, and an upper electrode formed on the organic compound layer, wherein the device separation film is a polyimide film having an imidation ratio in a range of 65% or more to less than 90%. The display is expected to have longer operating life.
