Abstract
The invention discloses a stacked storage capacitor structure for a LTPS TFT-LCD comprising a processed substrate, a first storage capacitor and a second storage capacitor. The first storage capacitor comprises a first conductive layer, a second conductive layer and a first insulating layer therebetween. The stacked storage capacitor structure further comprises a third conductive layer including a first portion and an extended second portion. The second storage capacitor comprises the second conductive layer, the extended second portion of the third conductive layer and a second insulating layer therebetween.
