Liquid crystal display having particular pixel structure

A liquid crystal display, comprising:

• a first substrate;
• a second substrate opposing to the first substrate;
• a liquid crystal layer sandwiched between the first substrate and the second substrate;
• a first alignment film disposed on the first substrate;
• and
• a second alignment film disposed on the second substrate;
• wherein the first substrate comprises:
• a plurality of scanning lines;
• and
• a plurality of data lines intercrossed with the plurality of scanning lines to define a plurality of pixel areas;
• wherein each pixel area comprises:
• a plurality of first electrodes which are electrically interconnected together;
• and
• a plurality of second electrodes which are electrically interconnected together, wherein the first electrodes and the second electrodes are disposed on different layers and mutually intersected to define a plurality of sub-pixel areas;
• wherein each sub-pixel area comprises two protrusion-shaped patterns facing each other and configured on two adjacent first electrodes where the first electrodes and the second electrodes are not overlapped;
• and
• wherein an angle within a range of 5-20 degrees is defined between a vertex connection direction of the two protrusion-shaped patterns facing each other and a rubbing direction of the first alignment film and the second alignment film.
