Abstract:
1. A thin-film transistor array substrate comprising: a thin-film transistor comprising: a pixel electrode disposed in an opening defined in the second insulating layer, wherein the pixel electrode comprises a transparent conductive oxide, and; a capacitor comprising: a pad electrode disposed on the second insulating layer, wherein the pad electrode comprises a material substantially the same as a material in the source electrode and the drain electrode; a first protective layer disposed on the pad electrode; and a second protective layer disposed on the first protective layer, wherein the first and second protective layer comprise different materials from each other, and different materials from the pad electrode, wherein the pad electrode has an upper surface, and the first and second protective layers cover the entire upper surface of the pad electrode, and wherein the first protective layer comprises an amorphous transparent conductive oxide.
