Abstract
The present invention relates to a liquid crystal display including: a lower electrode including a unit pixel electrode; an upper electrode including an upper unit electrode facing the unit pixel electrode; and a liquid crystal layer between the lower electrode and the upper electrode and including a plurality of liquid crystal molecules aligned approximately perpendicular to the surfaces of the lower electrode and the upper electrode in the absence of an electric field, wherein the unit pixel electrode includes a stem forming a boundary between a plurality of sub-regions and a plurality of minute branches extending in different directions in two different sub-regions, the upper unit electrode includes an opening facing the stem and extending parallel to the stem, any alignment aid to pretilt the liquid crystal molecules is absent, and a length of the minute branches is equal to or less than about 53 μm.
