Abstract
Diode for which one of the conducting layers presents a suitable surface resistance so that when a power supply voltage is applied between a connection element and this conducting layer and the other conducting layer, a potential distribution is generated at the surface of this resisting conducting layer which is able to cause light to be emitted by a portion of the surface of the organic light emitting layer which is proportional to this power supply voltage. This diode is advantageously used to visualize the signal value.
