ABSTRACT:
A light-emitting device comprises a stack of organic electroluminescent (EL) elements, wherein an organic EL element in the stack overlaps at least a portion of another organic EL element, and the organic EL elements are electrically separate. Each of the organic EL elements of the stack is activated with a different level of voltage.
