Abstract
The invention relates to a pixel for an active matrix display comprising an organic light emitting diode (OLED ) (19-23) and a driver circuit having a driver transistor that drives the light emitting diode (19-23) and having a capacitor, a current-carrying path of the driver transistor being connected in series with the light emitting diode (19-23) and at least indirectly between two poles of an operating voltage source. A transport layer (20) of the light emitting diode (19-23) is doped resulting in increased electrical conductivity of the transport layer (20) and is electrically connected to the drain contact (15) of the driver transistor.
