Abstract
A fringe field switching liquid crystal display (FFS-LCD) device (200) includes a first substrate (210) and a second substrate (220) disposed opposite to each other and spaced apart a predetermined distance, a liquid crystal layer (250) interposed between the first and second substrates, a plurality of gate lines (233) and data lines (234) formed on the second substrates, thereby defining a plurality of pixel regions, and a plurality of pixel electrodes (223) and a plate-like common electrode (221) provided in each of the pixel regions. The pixel electrodes have a plurality of curving comb portions so as to generate a continuous variation electric field between the pixel and common electrodes. Liquid crystal molecules in the FFS-LCD device are twisted in different continuous directions so as to reduce the color shift.
