Flat panel display having pad electrode
First Claim
1. A flat panel display, comprising:
- a substrate having a display portion; and
a pad arranged on the substrate and electrically coupled with the display portion, wherein the pad comprises;
a pad electrode arranged on the substrate;
a passivation layer arranged on the pad electrode and having a plurality of first contact holes that expose the pad electrode;
a reflective layer pattern arranged on the passivation layer and in the first contact holes, the reflective layer pattern having a plurality of second contact holes in portions of the reflective layer pattern in the first contact holes, the second contact holes exposing portions of the pad electrode exposed by the first contact holes; and
a transparent electrode arranged on the reflective layer pattern and the exposed portions of the pad electrode.

Abstract
A flat panel display, and method of fabricating the same, including a substrate having a display portion and a pad that is arranged on the substrate and is electrically coupled with the display portion. The pad includes a pad electrode arranged on the substrate, a passivation layer arranged on the pad electrode and having only one contact hole that exposes the pad electrode, and a transparent electrode arranged on the passivation layer and the pad electrode. The passivation layer may alternatively have a plurality of contact holes that expose the pad electrode. In this case, the reflective layer pattern is arranged on the passivation layer and the pad electrode, and it exposes portions of the pad electrode in the contact holes. Furthermore, the transparent electrode would be arranged on the reflective layer pattern and the exposed portions of the pad electrode.
