An image display device includes a display panel and a liquid crystal lens. The liquid crystal lens includes first and second zones equally distant from a center of the liquid crystal lens. The first zone, positioned at a left of the center, includes first linear electrodes. The second zone, positioned at a right of the center, includes second linear electrodes. A number of the first linear electrodes is equal to a number of the second linear electrodes. Bus lines are electrically connected to the first and second linear electrodes. A number of the plurality of bus lines is less than a sum of the number of the first linear electrodes and the number of the second linear electrodes.
