Abstract: The organic electroluminescence display device has a laminated portion on a base substrate. The device may have a cavernous portion formed by exploding a part of the laminated portion in a screening processing. A protective layer is formed to cover a whole surface of a wall defining the cavernous portion. Therefore, substances contained in the air are prevented from contacting to an organic electroluminescence layer at least partially defining the cavernous portion. Therefore, even if moisture is contained in the air, it is possible to prevent moisture from being absorbed by the organic electroluminescence layer. Moreover, since moisture is not absorbed by the organic electroluminescence layer, it is possible to reduce irregular spot on the device. In addition, it is possible to reduce a short circuit at an open defective portion.

Abstract: There is provided a polymer or low-molecular-weight compound multilayer type organic EL device configured such that a light-emitting layer formed on a hole transport layer includes a mixture of a polymer material and a low-molecular weight material. With such a configuration, the low-molecular-weight material added to the polymer material serves as a binder filling the gap of the steric hindrance to form entanglement of the polymer material and the low-molecular-weight material. This results in that the interface between the hole transport layer and the light-emitting layer is an interface high in adhesion and also high in carrier injectability. Further, optimization of the formation conditions and materials can achieve still higher reliability and longer lifetime.

Abstract: First and second insulating layers in an EL device are respectively composed of Al2O3/TiOx:Ba laminated layers. The Al2O3/TiOx:Ba laminated layers are formed by alternately laminating Al2O3 layers and TiO2 layers added with Ba by an ALE method. Adding Ba into the TiO2 layers mitigates a change in resistivity thereof with respect to a change in temperature. As a result, the EL device provides an excellent voltage withstanding performance which is stable against the changes in the temperature.
