    Abstract: When a protective film is formed so as to cover an electrode, a position of an end portion of the protective film is highly accurately adjusted. An electrode substrate includes a second substrate, and a sensing electrode continuously formed on the second substrate from a first region on an upper surface of the second substrate via a second region on the upper surface of the second substrate over a third region on the upper surface of the second substrate. Also, the electrode substrate includes a concave/convex pattern formed on the sensing electrode or the second substrate in the second region, and a protective film formed in the first region and the second region so as to cover the sensing electrode. An end portion of the protective film on the third region side is positioned on the concave/convex pattern.

    Abstract: A liquid crystal display device has a pair of wall electrodes facing each other, which is disposed on pixels on a first substrate, functions as one of pixel electrodes and a common electrode, and takes a posture of standing on the first substrate. Also, the liquid crystal display device has a center electrode that is disposed between the pair of wall electrodes, functions as the other of the pixel electrodes and the common electrode, has a convexity lower in height than the pair of wall electrodes, and makes a width in a direction along which the pair of wall electrodes faces each other gradually smaller toward the second substrate. According to this liquid crystal display device, since a vertical electric field can be prevented from being developed on an upper side of the center electrode, a transmittance of light can be improved.

    Abstract: The liquid crystal display device includes a pixel structure provided with a large wall formed along a long side of a pixel with a rectangular plane, a small wall formed at a center of the pixel and extending in the same direction as the large wall, a wall electrode formed on a wall surface of the large wall, a plane electrode formed between the small and large walls, in which the wall electrode and the plane electrode form a pixel electrode, and a common electrode formed on a surface of the small wall. The large wall has a part with an increased thickness at an end part of the pixel. The wall electrode is bent toward the center of the pixel. This structure prevents decrease of reverse twist of liquid crystal at an end part of the pixel as well as generation of domain, thus improving transmittance of the screen.

    Abstract: To reduce disturbances in display of images due to static electricity without deteriorating optical properties in a display. The display includes a conductive pattern provided on the upper surface of the substrate, a protection layer provided on the upper surface of the substrate to cover the conductive pattern, and a conductive layer provided on the protection layer. The sheet resistance of the conductive pattern is not more than 8 Ω/square. A ratio of the total sum of areas of portions of the plurality of sub-pixels that overlap the conductive pattern in a plan view to the total sum of the areas of the plurality of sub-pixels is 1 to 22%. A sheet resistance of the conductive layer is higher than the sheet resistance of the conductive pattern.
