    摘要: Provided is a top emission type organic light-emitting display device having the emission luminance thereof improved by increasing a quantity of electrons injected into an electron injection layer. At least a cathode, an electron injection layer, an electron transport layer, a light-emitting layer, a hole transport layer, and an anode are sequentially accumulated on an insulating substrate. The electron injection layer is formed with a co-deposited layer having both tris(8-hydroxyquinoline)aluminum (Alq3) and lithium (Li) evaporated thereon. The electron transport layer is formed with a deposited layer having tris (8-hydroxyquinoline)aluminum (Alq3) evaporated thereon. The ratio of Li to Alq3 in the co-deposited layer is equal to or larger than 1 and equal to or smaller than 3. The thickness of the co-deposited layer is equal to or larger than 1 nm and equal to or smaller than 3 nm. The thickness of the Alq3-deposited layer is equal to or larger than 5 nm and equal to or smaller than 7.5 nm. Consequently, a quantity of resistive components decreases, a current increases, and a quantity of electrons injected into the light-emitting layer increases (the electron mobility gets larger). Eventually, the emission luminance improves.

    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.

    摘要: The present invention ensures performance and reliability of a top-emission-type organic EL display device, reduces manufacturing steps by simplifying the structure of the display device, and reduces a manufacturing cost. TFTs each of which has a semiconductor layer, a gate insulation film which covers the semiconductor layer and a gate electrode 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, and a passivation film which covers the TFTs and the SD lines plays a role of a bank which separates pixels. 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.
