摘要:
To provide an electrode for an organic device which can realize a hole injection function and/or an electron injection function from a totally different point of view from metal donor doping. A composite material in which conductive particles of a particulate conductive inorganic compound (the diameter is 1 (nm) to 100 (nm), preferably, 1 (nm) to 20 (nm)) are dispersed in one or plural kinds of organic compounds 101 is layered on a surface of an organic layer 110 of an organic device where an electrode is to be formed to form an electrode for an organic device 100. As to the thus formed electrode, since the densely dispersed conductive particles 102 have large specific surface area, interaction between the conductive particles 102 and the organic compound 101 realizes a function of a donor or an acceptor. Besides, since adhesion with the organic layer 110 is high for the existence of the matrix of the organic compound 101, the electrode is suitable for an organic device.

There is provided a display element capable of efficiently emitting generated light externally and a method of manufacturing the display element, without damaging an organic electroluminescent layer. First, a transparent electrode protection material (11) is deposited on a first holding substrate (10); then organic electroluminescent light-emitting elements (12, 13, 14) are manufactured thereon; and then after sealing and holding with a sealing material (15) and a second holding substrate (16), the first holding substrate (10) and a transparent electrode protection material (11) are removed by etching or the like. According to the present invention, the removal of the first holding substrate (10) enables improvement of the emission rate generated in the electroluminescent layer (13), and improvement of brightness and contrast in the display element.

摘要:
An organic EL device that has good yields and high reliability as well as high current efficiency is provided by introducing the new concept to the conventional organic EL device structure. An EL device comprising a first electrode 101, a second electrode 102, an electroluminescent layer 103, conductive particles 104, wherein conductive particles 104 are dispersed in the EL layer 103, is used. Current efficiency will be increased since conductive particles serve as the conventional charge generation layer. In addition, fabricating processes will become simplified and fabricating costs will be reduced because the conductive particles and the EL layer can be formed simultaneously.

摘要:
There is provided a substrate for a light emitting device which includes an electrically conductive and transparent film which is in contact with a surface of a low refractive index member of which refractive index is greater than 1 and not greater than 1.30. In a preferable embodiment, the substrate further comprises a transparent member on its surface which is opposed to its surface which has the electrically conductive and transparent film. There is further provided a light emitting device which includes such substrate and a luminous layer, and the luminous layer is located on the electrically conductive and transparent film. With such light emitting device, a ratio of light which is withdrawn outside through the low refractive index member is increased, so that a coupling-out efficiency for surface emission of light withdrawn into the ambient air is increased.
