Abstract
An FFS (Fringe Field Switching) mode liquid crystal display comprises a lower substrate and an upper substrate and a gate line formed on the lower substrate. A data line crosses perpendicular to the gate line. A first ITO electrode is formed in a region defined by the gate line and the data line. A second ITO electrode of a comb-teeth pattern is formed on the lower substrate while being overlapped on the first ITO electrode. A black matrix formed on the upper substrate, wherein, a wedge portion of the second ITO electrode is formed at a position spaced by a predetermined interval to the inside from an edge section of the black matrix.
