摘要 |
<p>An organic electroluminescence device comprises an electron transport layer (5), an organic emitting layer (3) and an organic hole transport layer (4) laminated in sequence and arranged between a cathode (1) and an anode (2), is characterised in that the electron transport layer is made of a 1,10- or1,7- or 4,7-phenanthroline derivative or a 5,6-dihydro-dibenzo(bj)phenanthroline derivative. The electroluminescence device is capable of improved durability and emission of blue light at high luminance and high efficiency on application of a low voltage. <IMAGE></p> |
