A multi-domain IPS (in-plane switching) liquid crystal display (20) includes a first substrate (201), a second substrate (202), liquid crystal molecules (203) filled between the first and second substrates, and gate lines (211) and data lines (212) formed on the first substrate. The gate lines and data lines define pixel regions arranged in a matrix. Each pixel region includes pixel electrodes (233), common electrodes (243), and a TFT (thin film transistor) (220). The pixel electrodes and the common electrodes have a same curved shape, and are uniformly spaced apart from each other. Therefore the electric field generated by them is a smooth continuum of multiple domains, and the visual performance at various different viewing angles is equally good. Because the pixel and common electrodes do not have sharp bends, disclination is avoided. Therefore the IPS liquid crystal display has a high contrast ratio.

In summary, the first biaxial compensating film can compensate light in two perpendicular directions, thus improving contrast ratios in the two directions of the liquid crystal display and broadening a view angle of the liquid crystal display. Therefore, the liquid crystal display has an improved display performance.
