  • Publication number: 20110114981
    Abstract: In a light emitting display apparatus, excellent color reproducibility and high luminance for an emission color having a low color purity and low emission efficiency are realized. An electroluminescent layer whose color purity and emission efficiency are to be improved is stacked as a first layer on a substrate, and is interposed between a reflective electrode layer and a semi-reflective electrode, and then light extracted from the electroluminescent layer is intensified by interference between a reflective surface in the reflective electrode layer and a reflective surface in the semi-reflective electrode.
