Abstract
A light-emitting device includes a substrate, a plurality of bumps over the substrate; and a plurality of light-emitting units separated by the bumps. Each of the light-emitting units includes a first electrode on the substrate, an organic layer on the first electrode, and a second electrode on the organic layer. The light-emitting units comprise a first light-emitting unit and a second light-emitting unit, and the first light-emitting unit further includes an intermediate layer between the organic layer and the second electrode. The organic layer of the first light-emitting unit includes a first material, the second electrodes of the first light-emitting unit and the second light-emitting unit include an electrode material, and the intermediate layer of the first light-emitting unit includes the first material and the electrode material.
