摘要： TFTs are formed on a substrate. An interlayer insulation film is formed on the substrate to cover the TFTs. Lower layer portions of SD lines formed of a multi-layered film which are formed on the interlayer insulation film constitute a lower electrode of an organic EL layer. An uppermost layer of the SD line is formed of a chemically stable metal oxide film, and the SD layer is used as it is. On the other hand, as a lower electrode of an organic EL layer, an upper layer of the SD line is removed and an Al—Si, alloy film of the SD line is used. Due to such a constitution, it is possible to reduce a cost by shortening steps while holding the performance and the reliability of organic EL.

摘要： The invention allows a top-emission-type organic EL display device to use a chemically stable conductive film containing ITO for forming a lower electrode of an organic EL layer. The organic EL layer includes an electron injection layer, an electron transport layer, a light emission layer, a hole transport layer and a hole injection layer. An upper electrode which constitutes a transparent electrode is formed of an IZO film. A lower electrode adopts the two-layered structure consisting of a lower layer made of Al or an Al alloy having high reflectance and an upper layer formed of a chemically stable ITO film. To enable the injection of electrons from the ITO film which constitutes the lower electrode, the electron injection layer is formed using a film which is acquired by co-depositing Li and Alq3 at a molecular ratio of 3:1. Due to such a constitution, electrons can be injected from the ITO film thus realizing the top-emission-type organic EL display device.
