Abstract
An EC region (second region) of an organic EL display device () has an optical interference layer which is a multilayer of (i) an edge cover () made from an acrylic resin having a lower refractive index, (ii) an organic layer (), and (iii) a second electrode () which is a thin and semi-transparent film. Therefore, the organic EL display device () can suppress a deterioration in contrast without narrowing a display region, and can have a high reliability.
