Abstract:
An optoelectronic component may include a carrier, a first electrode over the carrier, an organically functional layer structure over the first electrode, a second electrode over the organically functional layer structure, and an encapsulation layer structure over the second electrode, the encapsulation layer structure encapsulating the organically functional layer structure and including a first layer structure facing toward the second electrode and a second layer structure facing away from the second electrode, the first layer structure alternately including first layers having a first expansion coefficient and second layers having a second expansion coefficient, which is not equal to the first expansion coefficient, and the second layer structure alternately including third layers having a third expansion coefficient and fourth layers having a fourth expansion coefficient, which is not equal to the third expansion coefficient.
