摘要： A solid-sealing type organic EL display device having an excellent mechanical strength, sealed by a highly reliable sealing method and in which the luminescence property is less deteriorated. A laminate film including a thermoplastic adhesive member and a barrier layer against moisture is disposed on an upper electrode that is situated over an organic EL layer. In a sealing part existed in a periphery of the display region, only a metal oxide film which is formed of metal alkoxide exists between an edge of the laminate film and the element substrate. The organic EL element is surrounded only by an inorganic film so that moisture permeation from the outside can be prevented. Moreover the sealing part is composed of the inorganic film having an excellent sealing property against water thereby it is possible to make a width of the sealing part small.

摘要： The present invention enhances the light utilization efficiency of an organic EL display device. A pixel electrode PXE is formed on a protective film PAS and first banks BNKA which are constituted of a first insulation layer are formed on the pixel electrode PXE in a convex shape. On the pixel electrode PXE, in a B1 region and a B2 region defined between a pair of first banks BNKA (A1 region, A2 region), second-1 banks BNKB-1 which are constituted of a second insulation layer and are slightly raised are formed. Further, on the second-1 banks BNKB-1, second-2 banks BNKB-2 which are constituted of the second insulation layer are formed. The second-2 banks BNKB-2 have an inverted-trapezoidal shape and surfaces of the second-2 banks BNKB-2 on sides which face the first bank BNKA have an inverted taper on a substrate side. Between the pair of first banks BNKA, functional layers OLE1, OLE2, OLE5 which constitute an organic EL light emitting element are formed on the pixel electrode PXE in a C1 region, a C2 region and a C3 region, and functional layers OLE2, OLE4 are respectively formed on the second-2 banks BNKB-2 in the B1 region and the B2 region. A counter electrode COUNT is formed in a state that the counter electrode COUNT covers all of these functional layers and is formed in common with a plurality of pixels.
