Abstract
An object of the present invention is to provide a bottom emission type organic EL display device that has a light-emitting element unit thereof protected from being damaged by a stored desiccant, that has a long service life, and that exhibits excellent display characteristics of a high luminance and a high contrast. The solution is such that the organic EL display device includes a desiccant assembly which is disposed on the internal side of a sealing substrate and which has a cushioning member thereof jutted out of the surface of a desiccant.
Claims6
An organic electroluminescent (EL) display device comprising organic EL display elements that include a lower electrode disposed on the major side of an element substrate, an organic EL layer which has a multilayer structure and is disposed on the lower electrode, an upper electrode disposed on the organic EL layer, a desiccant assembly opposed to the upper electrode with a predetermined space between them, a sealing substrate which holds the desiccant assembly and is opposed to the element substrate, and a sealant which joins the sealing substrate and element substrate, and that radiate light from the lower electrode side thereof, wherein:
- the desiccant assembly has a cushioning member jutted out of the surface of a desiccant toward the upper electrode.
