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.
