ABSTRACT:
A liquid crystal display has a storage capacitor of storage on common type in a pixel region with a passivation film of an inorganic insulating layer and an organic layer stacked on the inorganic insulating layer. The liquid crystal display includes: a storage capacitor lower electrode formed in the pixel region; a gate insulating layer formed on the storage capacitor lower electrode; the passivation film formed on the gate insulating layer, and a pixel electrode formed on the inorganic insulating layer. In the storage capacitance region of the pixel region, the organic insulating layer is partially or wholly removed and the pixel electrode functions as a storage capacitor upper electrode.
