Abstract: A liquid crystal material is driven in a twisted nematic mode so that while liquid crystal molecules lose, on a stripe electrode, rotary power toward a direction along an electric field by a voltage applied between the stripe electrode and a second electrode and form, in a region between the adjacent stripe electrodes, refractive index distribution of a lenticular lens that includes a cylindrical lens in which a cylindrical axis is arranged in a first direction. The cylindrical lens faces at least two rows of pixels, and has an effective refractive index for causing light from the at least two rows of pixels to advance in separating directions from each other after emission from a second polarizing plate. A distance d of a cell gap and an interval s between the adjacent stripe electrodes satisfy the relation of 3.5≦s/d≦7.

Abstract: In a three-dimensional display device using a liquid crystal lens, a planer electrode is formed on an upper substrate of the liquid crystal lens and strip-like electrodes are formed on a lower substrate of the liquid crystal display lens. The distance between the upper and lower substrates is provided by a bead. At this time, if the bead is present on the strip-like electrode, the lens formed thereon is distorted. In order to prevent this, a bump is formed to cover the strip-like electrode. The distance between the bump and the upper substrate is small, so that the bead is pushed out of the upper part of the strip-like electrode, preventing the lens from being distorted. As a result, it is possible to prevent the crosstalk caused by the lens distortion due to the presence of the bead on the strip-like electrode.
