    摘要: Provided is an organic EL device having a lower power consumption and high performance and enabling to display separate pictures on bidirectional screens as well as to display the same picture on the bidirectional screens, and a driving apparatus thereof. The organic EL device includes: a first organic EL panel for a unidirectional display; and a second organic EL panel for a unidirectional display, each of the first and second organic EL panels having a substrate, a first electrode, an emitting layer and a second electrode, wherein the first organic EL panel and the second organic EL panel are coupled so as to display pictures in bidirections. According to the present invention, a sufficient brightness can be obtained even under a low power. Also, since an opaque cathode is used, performance and transmittance are enhanced compared with the related art organic EL device using a transparent cathode.
