Electroluminescence device

An electroluminescence display device comprising:

• a first electrode formed over a substrate;
• a first electroluminescent film in contact with the first electrode;
• a second electrode in contact with the first electroluminescent film;
• a second electroluminescent film in contact with the second electrode;
• and
• a transparent third electrode in contact with the second electroluminescent film,
• wherein each of the first and second electroluminescent films comprises a hole injection layer, a hole transport layer, a electroluminescent layer, an electron transport layer, and an electron injection layer, and
• wherein an electric current flow direction through the first electroluminescent film is different from an electric current flow direction through the second electroluminescent film.

A mobile telephone comprising a display part, the display part having an electroluminescence display device, the electroluminescence display device comprising:

• a first anode formed over a substrate;
• a first electroluminescent film in contact with the first anode;
• a cathode in contact with the first electroluminescent film;
• a second electroluminescent film in contact with the cathode;
• and
• a transparent second anode in contact with the second electroluminescent film,
• wherein each of the first and second electroluminescent films comprises a hole injection layer, a hole transport layer, a electroluminescent layer, an electron transport layer, and an electron injection layer, and
• wherein an electric current flow direction through the first electroluminescent film is different from an electric current flow direction through the second electroluminescent film.
