Liquid crystal display and method thereof

A liquid crystal display comprising:

• a first substrate and a second substrate facing each other;
• a plurality of pixel electrodes arranged in a matrix shape on the first substrate and including a stem and a plurality of minute branches obliquely extending from the stem;
• a common electrode facing the plurality of pixel electrodes;
• and
• a liquid crystal layer interposed between the first substrate and the second substrate and including a plurality of liquid crystal molecules,
• wherein the pixel electrodes are classified into a plurality of sub-regions according to a length direction of the minute branches, and a first groove is disposed according to the length direction of the minute branches between the minute branches.

A method of improving response speed of a liquid crystal display, the method comprising:

• arranging a plurality of pixel electrodes in a matrix shape on a first substrate of the liquid crystal display, each pixel electrode including a stem and a plurality of minute branches obliquely extending from the stem, the pixel electrodes classified into a plurality of sub-regions according to a length direction of the minute branches;
• interposing a liquid crystal layer between the first substrate and a second substrate of the liquid crystal display;
• and,
• protruding the minute branches at edges of the sub-regions towards the second substrate.
