Abstract: A sensing circuit is configured to measure a first physical quantity corresponding to a first capacitance being a parasitic capacitance formed in at least one of electrode groups including a plurality of first electrodes and a plurality of second electrodes, to thereby detect that significant change has occurred in the first capacitance due to touching of a conductor when an obtained first measurement value is out of a first range. The sensing circuit is further configured to measure a second physical quantity corresponding to a second capacitance formed between each of the plurality of first electrodes and each of the plurality of second electrodes, to thereby detect that significant change has occurred in the second capacitance due to compression of an insulating elastic layer based on a pressing force when an obtained second measurement value is out of a second range.

The three dimensional image display device includes a display panel on which rows of pixels for right eye and rows of pixels for left eye are alternately arranged in a lateral direction, the display panel planarly displaying an image for three dimensional display, and a parallax forming liquid crystal panel for forming a parallax in an image for right eye and an image for left eye displayed by the display panel. Lateral direction center positions, which are vertexes of luminance in the lateral direction of an image for right eye and an image for left eye, where the image for three dimensional display is visually sensed through the parallax forming liquid crystal panel, are respectively positions shifted in the lateral direction in different positions in the screen longitudinal direction.

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.

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.

Second electrodes are formed on an insulation surface in such a manner that the adjacent second electrodes are connected in the second direction and are separated in the first direction. Third electrodes are formed in regions in which the third electrodes overlap with the first electrodes and do not overlap with the second electrodes in such a manner that the adjacent third electrodes are connected in the second direction and are separated in the first direction. A flexible insulation layer is formed between the first electrodes and the third electrodes. An area of each of the third electrodes is less than an area of each of the first electrodes.
