| 摘要 |
<p>The present organic EL devices have at least one luminescent layer and a cathode sequentially provided on their anode, which luminescent layer contains an electron-transporting material, a hole-transporting material, and a luminescent dopant. Preferably, an electron-transporting layer is further provided between the luminescent layer and the cathode. According to the present invention, organic EL devices can be provided giving improved whiteness, colour reproducibility, luminescent efficiency, and lifetime compared to conventional ones.</p> |
