摘要： The present invention provides an organic EL display device which has a long lifetime. The organic EL display device includes a plurality of pixels each of which is constituted of a top-emission-type active matrix organic EL element. The EL element includes: a pixel electrode; a reflective layer arranged between the pixel electrode and an active element and is formed over a leveling layer; an organic light emission layer; and a common electrode. The reflective layer includes: a first reflective layer which is made of high-melting-point metal; and a second reflective layer which is arranged on the first reflective layer. The second reflective layer includes a planar pattern in which an outer periphery of the second reflective layer is surrounded by the first reflective layer. The pixel electrode extends outward from the first reflective layer and the second reflective layer.

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.
