Abstract
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, a second electrode, an electroluminescent layer, conductive particles, wherein conductive particlesare dispersed in the EL layer, 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.
