Abstract: A thin film transistor array substrate and its manufacturing method are disclosed. A thin film transistor (TFT) includes a gate electrode formed on a substrate, and source and drain electrodes formed on the gate electrode and separated from each other. A common line made of the same material as the gate electrode is formed on the substrate. A storage capacitor includes a storage electrode connected with a storage electrode line and a pixel electrode formed on the storage electrode. The storage electrode and the pixel electrode are formed by patterning a transparent conductive film, and accordingly, light can be transmitted through the region where the storage capacitor is formed to thus increase an aperture ratio.

Abstract: In manufacturing a thin film transistor array substrate, a passivation film is formed over the transistors. A first photoresist pattern is formed over the passivation film, with a first portion partially overlying at least one source/drain electrode of each transistor and overlying each pixel electrode region, and with a second portion thicker than the first portion. The passivation film is patterned using the first photoresist pattern as a mask. The first photoresist pattern's first portion is removed to form a second photoresist pattern which protrudes upward around the pixel electrode regions. A transparent conductive film is formed with recesses in the pixel electrode regions. A masking pattern is formed over the transparent film in each pixel electrode region, the masking pattern's top surface being below a top of the transparent film. The transparent film is patterned using the masking pattern as a mask to form the pixel electrodes.
