1. A display device, comprising:
an isolation structure disposed over a reflector electrode;
an additional electrode disposed over the isolation structure;
an optical emitter structure disposed over the additional electrode; and
a via structure comprising 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, wherein the upper horizontal segment is connected to the lower horizontal segment by the vertical segment.
