摘要:
An organic electro-luminescence display device emits light by applying a voltage by an image signal between an upper electrode (23) and a lower electrode which sandwich an organic electro-luminescence layer. The organic electro-luminescence layer comprises an electron transporting layer, a light emitting layer, and a hole transporting layer. The electron transporting layer includes an organic material and cesium, and has a moisture absorbing characteristic. A structure in which the same materials as the electron transporting layer are used and which has a different constituent composition and a greater amount of cesium is used as a desiccant (40) and placed in a region which does not overlap the organic electro-luminescence layer, to effectively remove moisture inside the organic electro-luminescence display device.
