摘要：
The invention relates to a light-emitting diode comprising an anode, a cathode, a light-emitting layer, and at least one charge transport layer which has a luminescence efficiency which is at least 25% of the luminescence efficiency of the light-emitting layer. This leads to a light-emitting diode with a smaller percentage of catastrophic failures than in existing LEDs, because the charge transport layer takes over the light emission in case of a short-circuit of the light-emitting layer.
