Abstract
Provided is a three-dimensional image display device which allows a favorable three-dimensional image to be recognized without generating flicker even under a movement of the line of sight. A liquid crystal parallax barrier panel is arranged on a display panel. The liquid crystal parallax barrier panel includes a barrier substrate having barrier electrodes formed thereon, a common substrate provided with a common electrode, and liquid crystal held between the barrier substrate and the common electrode. Barriers are formed by applying a voltage to the barrier electrodes. Where τon represents a time required to form barriers on the barrier electrodes after a voltage is applied to the barrier electrodes and τoff represents a time required to cancel the barriers after the voltage is removed from the barrier electrodes, a value of (τoff−τon) is 15 milliseconds or less, preferably 10 milliseconds or less.
