Abstract: Disclosed are a wide-viewing-angle liquid crystal display and a display method thereof, so as to improve the color cast problem generated during displaying by the wide-viewing-angle liquid crystal display. ITO slots of two or more directions are provided on a public electrode corresponding to a pixel electrode in a hollowed-out mode, so that liquid crystal molecules can be displayed in a multi-domain mode and are compensated from different viewing angles, and the fluctuation of liquid crystal molecules for the light refraction under an oblique angle is reduced, thereby improving the displaying effect of the wide-viewing-angle liquid crystal display.
