Claim:
1. An organic light-emitting diode (OLED) display, comprising: a substrate including a display region and a peripheral region; a switching element formed over the substrate, wherein the switching element includes an active layer, a gate insulating layer, a gate electrode, an insulating interlayer, a first electrode, and a second electrode; a first insulating layer formed over the switching element; a first auxiliary electrode formed over one region of the first insulating layer that substantially overlaps the peripheral region; a second insulating layer formed over the first insulating layer, the second insulating layer exposing a portion of an upper surface of the first auxiliary electrode and covering both lateral portions of the first auxiliary electrode; an anode electrode formed over a first region of the second insulating layer that substantially overlaps the display region, wherein the anode electrode is electrically connected to the first electrode of the switching element via a first opening; a protecting electrode formed apart from the anode electrode on a second region of the second insulating layer that substantially overlaps the peripheral region, wherein the protecting electrode is electrically connected to the first auxiliary electrode via a second opening, and wherein the protecting electrode covers the portion of the upper surface of the first auxiliary electrode such that the first auxiliary electrode is not exposed; a pixel defining layer formed over the second insulating layer, wherein the pixel defining layer separates the display region and the peripheral region and covers both lateral portions of the first auxiliary electrode and both lateral portions of the anode electrode; an emission layer formed over the anode electrode; and a cathode electrode formed over the protecting electrode, the pixel defining layer, and the emission layer.
