Abstract: A pixel unit at a TFT-LCD array substrate includes a thin film transistor, a first storage capacitor, and a second storage capacitor. The first storage capacitor includes a transparent common electrode, a pixel electrode, and a first insulating layer disposed between the transparent common electrode and the pixel electrode. The second storage capacitor includes a first conductive layer, a second conductive layer, and a second insulating layer disposed between the first and second conductive layers. The first conductive layer is connected to the transparent common electrode within the pixel unit. The second conductive layer is connected to the pixel electrode within the pixel unit.
