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.

Abstract: The liquid crystal lens is formed by placing a TN type liquid crystal with a twist angle of 90 degrees between the first and second substrates. A first substrate having a flat surface with a slit is formed on the liquid crystal side of the first substrate, and a second electrode having a comb electrode, as seen in a plane view, is formed on the liquid crystal side of the second substrate. The slit formed in the first electrode extends in the same direction as the comb electrode of the second electrode, and the slit is located in the center between the comb electrodes of the second electrodes as seen in a plane view, to prevent the electric lines of force, moving from directly above the second electrode to the first electrode, from spreading in the plan direction, thereby preventing light leakage directly above the second electrode.

Abstract: An image display device includes a liquid crystal lens on a display surface side of a display panel. The liquid crystal lens includes a first substrate, a second substrate, a liquid crystal layer interposed between the first substrate and the second substrate, a first alignment film and a second alignment film formed on an interface of the liquid crystal layer. The first alignment film and the second alignment film are alignment films subjected to a rubbing treatment so that liquid crystal molecules in the liquid crystal layer are aligned in a 90° twist in a first direction by the provision of a pretilt angle. The liquid crystal molecules are aligned, by the addition of a chiral agent to the liquid crystal layer, in a 90° twist in a second direction opposite to the first direction in a state where an electric field is not applied.
