摘要： 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.

摘要： According to the invention, after a transparent electrode is vapor-deposited over the entire color-filter side surface, a non-conductive film is laid where the presence of the transparent electrode causes problems. That is, this non-conductive film is formed of the same material and at the same time as an alignment regulation film over the whole or a part of the area where exposure of the transparent electrode causes problems so as to seal the transparent electrode there. This makes it possible to prevent the above-mentioned problems caused when the transparent electrode is vapor-deposited over the entire surface, and simultaneously to enhance the patterning accuracy up to the exposure accuracy (of the order of several μm) of proximity or the like so as to realize a product with a narrow frame.
