An organic EL device is disclosed, which has an organic multilayer between a first electrode and a second electrode, the organic multilayer comprising a hole injection layer formed on the first electrode, and formed of a mixture of at least one selected from organic materials and at least one selected from inorganic materials; a hole transport layer having at least one layer on the hole injection layer; and an emitting layer formed on the hole transport layer.

Organic el device

An improved organic electroluminescent device is provided. The device may include a protection layer provided on non-light-emitting regions of a panel to prevent reflection of external light. The protection layer may include an optical filter used in combination with a black insulator. The protection layer may provide for improved reflectance and transmissivity, and improved brightness without a commensurate reduction in contrast.

Organic electroluminescent device with black insulator

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.
