  • Patent number: 8120743
    Abstract: A production method of a liquid crystal display device that is constructed by placing liquid crystals between a first substrate and a second substrate. The production method includes a step of applying seal material onto the first substrate such that the seal material surrounds a liquid crystal filling area, and a step of bonding the first substrate and the second substrate together. The layer of the seal material is formed such that the thickness becomes smaller than the thickness of the liquid crystal layer in the portion corresponding to the display area when the first substrate and the second substrate are bonded together.

  • Patent number: 7948598
    Abstract: Disclosed herein is a method of manufacturing a liquid crystal display device of dropping liquid crystals to be interposed between a first substrate and a second substrate to one of the substrates. The method includes a step of applying the sealant to one of the substrates where a region closed by the sealant is formed by a sealant on the main surface of the substrate, and, in this closed region, a liquid crystal filling region as a display region and a capturing region to the outer periphery of the liquid crystal filling region for intaking surplus liquid crystals or voids are formed.

  • Patent number: 7052995
    Abstract: A buried film and a barrier film are polished together using a slurry in which the polishing rate on a substrate material (in particular, silicon oxide), that on a buried-film material (in particular, tungsten) and that on a barrier-film material (in particular, titanium oxide) are substantially equal to one another. This can materialize a buried structure free from any step or steps, at a high polishing rate.

  • Patent number: 6753048
    Abstract: A material for a liquid-crystal alignment film which comprises as a first polyamide a C3 to C10 alkyl ester of a polyamic acid whose acid anhydride residual group is any of: and as a second polyamide a C3 to C10 alkyl ester of a polyamic acid whose acid anhydride residual group is: is provided. The use of this material materializes a liquid-crystal alignment film having a high pre-tilt angle of molecules to the substrate, and having superiority in respect of electrical properties such as voltage holding ratio and residual DC voltage, adherence to substrates, printability, and step-covering properties.

  • Patent number: 5925444
    Abstract: A multilayer ceramic substrate comprising at least one ceramic layer made by laminating at least one ceramic green sheet layer and conductor layers formed on surfaces of the at least one ceramic green sheet layer into laminates and by sintering the resulting laminates. Each ceramic green sheet layer comprises a ceramic precursor composition comprising (I) 100 parts by weight of ceramic fine powder having an average particle diameter of 10 microns or less as component (C) and (II) 5 to 30 parts by weight, based on 100 parts by weight of the ceramic fine powder, of an organic binder for bonding the ceramic fine powder. The organic binder comprises (i) 100 parts by weight of a water insoluble polymer of at least one vinyl monomer as a major component of the organic binder, as component (A), and (ii) 1 to 9.5 parts by weight, based on 100 parts by weight of the component (A), of water soluble polymer as component (B).
