Abstract

In some embodiments, the present disclosure relates to a display device. The display device includes an isolation structure disposed over a reflector electrode, an additional electrode disposed over the isolation structure, and an optical emitter structure disposed over the additional electrode. A via structure includes a lower horizontal segment disposed on the reflector electrode, a vertical segment extending along a sidewall of the isolation structure, and an upper horizontal segment disposed over the isolation structure. The upper horizontal segment is connected to the lower horizontal segment by the vertical segment.
