A liquid crystal display device comprising:
- a substrate;
- a thin film transistor on the substrate;
- a pixel electrode having a plurality of first tips, the first tips being formed on at least one edge of the pixel electrode;
- and
- a common electrode having a plurality of second tips, the second tips being formed on at least one edge of the common electrode, and whereby an electric field is created relative to said pixel electrode and said common electrode having a threshold voltage in direct relation to a distance from an apex of one of said first tips to the at least one edge of said common electrode, wherein the distance from the apex of said first tip to the at least one edge of said common electrode is less than the distance between the pixel and common electrodes creating a uniform electric field.
