Multi-domain liquid crystal display having concave virtual bump structures

A multi-domain liquid crystal display comprising:

• a first substrate with a pixel electrode layer formed above said first substrate;
• a second substrate coated with a passivation layer underneath;
• a common electrode layer formed below said passivation layer;
• at least one concave structure formed in each pixel area on said common electrode layer, said passivation layer being dented by said concave structure;
• and
• a liquid crystal layer with liquid crystals filling a space between said pixel and common electrode layers;
• wherein said at least one concave structure has a top void with a width ranging from 0.5 μm to 20 μm and a depth ranging from 100 to 1000 angstroms.
