Abstract
The present invention provides a manufacturing method of an image TFT array, which includes providing a substrate including a thin film transistor region, a storage capacitor region, a pad region, and a common electrode region, forming a photoresist layer on the substrate, and performing a photolithographic and etching process by utilizing a half-tone mask to pattern the photoresist layer to define a position of a through hole on the storage capacitor region and form the photoresist layer of a first thickness on the thin film transistor region and the photoresist layer of a second thickness on the region between the thin film transistor region and the storage capacitor region, wherein the first thickness is greater than the second thickness.
