Abstract
A thin film transistor (TFT) array includes a substrate, a thin film transistor, a first wall, a transparent electrode and a color resist. The thin film transistor is disposed on the substrate. The first wall is disposed on the substrate and separates a first contact hole from a pixel region on the substrate, wherein the first contact hole exposes a drain electrode of the thin film transistor. The first wall has a first sidewall facing towards the first contact hole and a second sidewall facing towards the pixel region, wherein the slope of the first sidewall is gentler than the slope of the second sidewall. The transparent electrode is electrically connected to the drain electrode of the thin film transistor through the first contact hole. The pixel region is filled with the color resist.
