Abstract

A method of making a light-emitting device comprises forming a first and second components. The first component has a first substrate, a first electrode on the first substrate, an organic layer on the first electrode, and a light-transmissive second electrode on the organic layer. The second component has a light-transmissive second substrate, and a light transmissive, electrically conductive layer on the second substrate. The first and second components are joined with the second electrode of the first component facing the conductive layer of the second component. An electrical contact is formed between the second electrode of the first component and the electrically conductive layer of the second component.
