Abstract

A liquid crystal display includes: a first substrate; a first signal line formed on the first substrate and extending in a direction; a second signal line intersecting the first signal line while being insulated; a pixel electrode formed in a pixel area defined by intersections of the first signal line and the second signal line, the pixel electrode having a plurality of partitions; a switching element connected to the first signal line, the second signal line, and the pixel electrode; a second substrate opposite the first substrate; a black matrix formed on the second substrate; and a common electrode formed over the second substrate having a plurality of domain defining members, wherein each domain is enclosed by the partitions of the pixel electrode and the domain defining members and has at least one long side parallel or perpendicular to the first signal line and at least one short side curved at an angle of about 30 to about 60 degrees with the first signal line.
