Storage capacitor structure

A liquid crystal display device, comprising:

• a plurality of scan lines;
• a plurality of signal lines;
• and a plurality of pixels with each pixel having a liquid crystal cell, a pixel electrode connected to a storage capacitor and a switching element connected to one of the liquid crystal cells and the signal lines, wherein each switching element is connected to one of the scan lines;
• wherein the pixel electrode has a protruding section such that the pixel electrode is electrically connected to an upper electrode of the storage capacitor through the protruding section.

A method of fabricating a storage capacitor, comprising the steps of:

• providing a substrate;
• forming a first capacitor electrode over the substrate;
• forming a capacitor dielectric layer over the first capacitor electrode;
• forming a second capacitor electrode over the capacitor dielectric layer, wherein the first capacitor electrode, the capacitor dielectric layer and the second capacitor electrode together form the storage capacitor;
• forming a passivation layer over the second capacitor electrode;
• patterning the passivation layer to form an opening that exposes a portion of the second capacitor electrode;
• and forming a pixel electrode layer over the passivation layer, wherein the pixel electrode layer has a protruding section such that the pixel electrode and the second capacitor electrode are electrically connected through the opening in the passivation layer, and the protruding section may be cut to detach the pixel electrode layer from the second capacitor electrode.
