An optically compensated bend (OCB) mode liquid crystal display (LCD) includes a liquid crystal display having a first substrate, a first electrode forming on the first substrate, a second substrate facing the first substrate, a second electrode formed on the second substrate and facing the first electrode, a liquid crystal layer formed between the first and second electrodes and filled with liquid crystals, and a plurality of charge supplying units supplying charges to the first electrode several times to apply a bend voltage for transiting an arrangement of the liquid crystals.
