A display substrate includes a substrate, a first conductive member, a second conductive member, an alignment film, an insulator, and a contact hole filler. The substrate includes a display area and a non-display area surrounding the display area. The first conductive member is disposed in the non-display area. The second conductive member is disposed in upper than the first conductive member to partially overlap the second conductive member in the non-display area. The alignment film is disposed upper than the second conductive member to straddle the display area and the non-display area. The insulator is disposed between the first conductive member and the second conductive member in the non-display area. The insulator includes a contact hole in a section overlapping the first conductive member and the second conductive member. The contact hole filler is disposed upper than the second conductive member to fill the contact hole.

Display substrate and display device

The present invention provides a liquid crystal display that can suppress generation of defects even when attachment misalignment of substrates is generated, and that is advantageous in providing high definition. The present invention relates to a liquid crystal display including: a first substrate; a second substrate; and a liquid crystal layer sandwiched between the first and second substrates, the first substrate including an interlayer insulating film in which multiple openings are formed on the same straight line, the interlayer insulating film including multiple curved portions each provided with a curved upper surface, the curved portions each positioned between two adjacent openings, the second substrate provided with a spacer facing at least one of the curved portions, the spacer being longer in a first direction than in a second direction wherein the first direction is a direction parallel to the straight line, and the second direction is orthogonal to the first direction.

Liquid crystal display

A liquid crystal sealant comprising an epoxy resin represented by the following formula (1): [Formula 1] (in the formula, n denotes an average polymerization degree and is a positive number of 0&#x2013;5) as a resin component, a curing agent, a curing accelerator and an inorganic filler is excellent in screen printability as a liquid crystal sealant in making a liquid crystal display device and can provide excellent reliability in moisture resistance for the liquid crystal display device obtained).

Liquid crystal sealant, liquid crystal display device using the same and method for producing the device

It is an object of the invention to provide a liquid crystal display apparatus in which the cell gap is uniform and the display quality is high, and also a method for manufacturing the same. In the liquid crystal display apparatus, a color filter side substrate in which a protrusion is formed by a black mask, and a TFT side substrate in which a recess is formed by a resin film such as an orientation film are bonded together via dispersed spacers therebetween, and a liquid crystal is filled between the substrates. In the resin film such as an orientation film, patterning is performed except a portion which is opposed to the protrusion, thereby forming the recess in the TFT side substrate. The formation of the recess prevents the cell gap from being pushed up even when the dispersed spacers are placed on the protrusion. Even in the case where the substrates are not flat, therefore, the cell gap can be maintained uniform.

Liquid crystal display apparatus and method for manufacturing same

A substrate bonding method in which a pair of masks which were prepared by forming a recessed section at a center part of each flat plate are placed on upper and lower stages, respectively, so that the recessed sections face a CF substrate and a TFT substrate, the CF substrate and TFT substrate are positioned one upon another and bonded together by sandwiching them between the masks. With this method, not only the CF substrate and TFT substrate are protected by the recessed sections from both sides, but also the dimensions of a region of each of the CF substrate and TFT substrate protected by the recessed sections are easily changed by replacing the masks. It is thus possible to provide a substrate bonding method that can readily meet the manufacture of bonded substrates of a variety of dimensions.
