Patent ID: 8106582

Claim:
An organic electroluminescent display comprising: a substrate; and a first organic electroluminescent device part and a second organic electroluminescent device part placed side by side on a surface of the substrate; the first organic electroluminescent device part including at least a light reflective conductive layer, a first metal oxide layer, an organic luminescent medium layer, and a transparent electrode layer in this order and including a light reflective layer inside or outside of the organic luminescent medium layer or the transparent electrode layer; the second organic electroluminescent device part including at least a light reflective conductive layer, a first metal oxide layer, a second metal oxide layer, an organic luminescent medium layer, and a transparent electrode layer in this order and including a light reflective layer inside or outside of the organic luminescent medium layer or the transparent electrode layer; the second metal oxide layer being able to be etched more easily than the first metal oxide layer, wherein at least one metal oxide compound in the first metal oxide layer is a different compound from a metal oxide compound in the second metal oxide layer, or vice-versa; and an emission spectrum of light from the first organic electroluminescent device part differing from an emission spectrum of light from the second organic electroluminescent device part.
