Abstract
A liquid crystal display includes a first substrate facing a second substrate, a liquid crystal layer between the first and second substrates, a first electrode disposed on the first substrate and being planar, and a second electrode disposed on the first substrate with branch electrodes overlapping the first electrode. The branch electrode includes boundary regions disposed at opposing ends thereof and at least two main regions disposed between the boundary regions. The main regions include a first main region adjacent to a second main region. A first angle, formed by the branch electrode in the first main region with respect to a first direction, is different from a second angle formed by the branch electrode in the second main region with respect to the first direction. A third angle, formed by the branch electrode in the boundary regions with respect to the first direction, is larger than the first and second angles.
