Abstract: A multi-color light-emitting element has at least two optical micro-cavity structures (102-106) having respectively different optical lengths determining their emission wavelengths. Each micro-cavity structure contains a film (105) of organic material as a light-emitting region. These may be a single film (105) of uniform thickness in the element.
