A three dimensional image display includes a display panel and a liquid crystal lens positioned on the top of the display panel. The liquid crystal lens comprises a lower substrate, an upper substrate, a lens, and an electrode voltage applying IC. The lower substrate includes a first electrode. The upper substrate includes a second electrode. The upper substrate faces the lower substrate. The lens liquid crystal layer is positioned between the lower substrate and the upper substrate. The electrode voltage applying IC is configured to form a plurality of zones on the first electrode of the lower substrate by sequentially applying first voltage and second voltage to the first electrode. The first voltage includes an overshoot voltage level. The second voltage has an inverted polarity of the first voltage.
