ORGANIC ELECTROLUMINESCENT ELEMENT AND FLAT-PANEL DISPLAY |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a white light-emitting device with high efficiency. <P>SOLUTION: A light-emitting device comprises: an anode; a first organic thin film formed on the anode; an organic semiconductor layer doped with a donor formed on the first organic thin film; an organic semiconductor layer doped with an acceptor formed on the organic semiconductor layer doped with the donor; a second organic thin film formed on the organic semiconductor layer doped with the acceptor; and a cathode formed on the second organic thin film. The first organic thin film and the second organic thin film emit light, and the mixture color of the first organic thin film and the second organic thin film is white. <P>COPYRIGHT: (C)2012,JPO&INPIT |
