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 translation: 通过在第一和第二基板之间放置扭转角为90度的TN型液晶来形成液晶透镜。 在第一基板的液晶侧形成有具有狭缝的平坦面的第一基板，在第二基板的液晶侧形成有如俯视图所示的具有梳形电极的第二电极。 形成在第一电极中的狭缝沿与第二电极的梳状电极相同的方向延伸，并且如平面图所示，狭缝位于第二电极的梳状电极之间的中心，以防止电线 从第二电极的正上方移动到第一电极的力在平面方向上扩展，从而防止直接在第二电极上方的光泄漏。

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.
