Multi-domain liquid crystal display

A multi-domain liquid crystal display, comprising:

• a first and a second substrates;
• a liquid crystal layer having negative dielectric anisotropy interposed between the first and the second substrates;
• a common electrode formed on an entire surface of the first substrate;
• a Metal 1 layer formed on the second substrate and patterned to define first signal lines and the gate of a thin film transistor;
• a first dielectric layer formed overlying the Metal 1 layer;
• a Metal 2 layer formed on the first dielectric layer and patterned to define second signal lines and the drain and the source of the thin film transistor;
• a second dielectric layer formed overlying the Metal 2 layer;
• a plurality of pixel electrodes formed on the second dielectric layer;
• a third dielectric layer formed overlying the pixel electrodes;
• and
• a Metal 3 layer formed on the third dielectric layer, wherein the Metal 3 layer is patterned to define a first and a, second parts apart from each other, the first part is connected to the common electrode to produce fringe fields, and the second part is surrounded by the first part and formed as a reflective layer.
