    Abstract: Provided is a liquid crystal display panel in which both the prevention of low-temperature bubble defects and the prevention of unevenness in brightness by pressure can be achieved without the need of forming multiple types of spacers differing in the height. In a liquid crystal display panel comprising a plurality of spacers 14 arranged between a pair of transparent substrates 11 and 12 and a liquid crystal 13 encapsulated between the transparent substrates, the spacers 14 are of a uniform height and each spacer 14 is substantially in a trapezoidal shape in which the ratio between the top area and the bottom area is 0.3 or less. The spacers 14 are formed on one of the transparent substrates 11 and 12. The spacers 14 are arranged at appropriate density so that the contact area ratio of the spacers' top surfaces in contact with the opposing substrate per unit area is within a range of 0.8%-1.0%.

    Abstract: An electrode substrate includes a sensing electrode formed on a glass substrate, a concave/convex pattern formed on the glass substrate, and a protective film formed so as to cover the sensing electrode. The concave/convex pattern is disposed closer to an outer periphery of the glass substrate than the sensing electrode is when seen in a plan view. The protective film is formed so as to cover a part of the glass substrate positioned between the sensing electrode and the concave/convex pattern when seen in a plan view.

A liquid crystal display device includes a plurality of pixels arranged in a matrix, each of the pixels having an insulator wall structure formed at a border of pixels, a wall electrode formed at a side surface of the wall structure of the border of the pixels, a source electrode which is continuous with the wall electrode and formed of a planar electrode extending in a planar direction, a first common electrode provided between source electrodes at both sides of the pixel to form a retentive capacitance, and a second common electrode provided between wall electrodes on both sides of the pixel. A slit which becomes a border of the wall electrodes of two adjacent pixels is disposed only on a top of the wall structure.

    Abstract: A first electrode 30 for the touch panel is formed on an outer side of a counter substrate 200, and the protection film 210 is formed over the first electrode 30 to cover it. A defect 211 in the protection film 210 is filled in with another protection film 210 by inkjet coating. The surface of the protection film 210 is rubbed to a rough surface finish. The polarization plate 220 is attached to the rough surface of the protection film 210 via an adhesive material 221. Since the defective region is repaired by the formation of the protection film 210, corrosion of the first electrode (wiring) 30 due to the presence of the adhesive material 221 can be prevented, and since the surface of the second protection film 210 is made rough, a resulting increase in adhering surface area enhances the adhesion for attaching the polarization plate 220.
