Abstract: In a three-dimensional display device employing liquid crystal lenses, the crosstalk caused by disclination occurring in the liquid crystal lenses is prevented. The liquid crystal lens includes a liquid crystal of the TN type having a twist angle of 90 degrees, the liquid crystal being sandwiched between a first substrate and a second substrate. A first electrode in a flat shape is formed on the first substrate to substantially cover the first substrate. Second electrodes shaped like comb teeth are formed on the second substrate. Each of the second electrodes is formed on the top of a projection formed on the second substrate. Three-dimensional display is performed by applying voltage between the first and second electrodes. The second electrode may be formed also on side faces of the projection. With this configuration, a three-dimensional image display device with less crosstalk can be realized.
