  • Patent number: 9229559
    Abstract: A display device (100) of the present invention is configured in such a manner that a liquid crystal module (30) is inserted in the inside (of the inner faces) of a positioning frame (20) that is attached to a top window (10). This eliminates the need to consider a positioning tolerance for the attachment. As a result, the display device can be reduced in size and a narrow frame can be achieved.
    Type: Grant

  • Patent number: 8994909
    Abstract: The width W1 of a groove (5a) is formed narrower than the width W2 of a groove (6a). The width W2 of the groove (6a) is formed at a prescribed width such that a sealing material (8) that overflows the groove (5a) can be formed along the groove (6a). The sealing material (8) spreads across the entirety of the groove (5a) and the groove (6a) when a color filter substrate (2) and an active matrix substrate (3) are bonded together. The groove (5a) is formed so as to be positioned within the groove (6a) in a plan view.

  • Patent number: 8330929
    Abstract: A display panel includes a first substrate in which a terminal area is defined along at least one edge thereof, and connection terminals are formed in the terminal area; and a second substrate which is bonded to the first substrate with sealing material being interposed between the first and second substrates, so as to expose the connection terminals. At an edge of the second substrate corresponding to the edge of the first substrate, at which the terminal area is defined, the second substrate includes protrusions protruding to the edge of the first substrate.

  • Patent number: 8325319
    Abstract: A method for manufacturing a liquid crystal display panel includes applying a first frame-like sealing material, and a second sealing material adjacent to the first sealing material along at least one side of the first sealing material, on a first mother substrate; forming a spacer on a second mother substrate made of glass so as to extend between the first and second sealing materials; bonding the first mother substrate on which the first and second sealing materials are applied, and the second mother substrate on which the spacer is formed, to each other such that the first and second sealing materials are in contact with each other without gaps with the spacer being interposed therebetween, and that a liquid crystal layer is sealed within the frame defined by the first sealing material; and cutting the bonded mother substrates at an intermediate position in the width direction of the spacer.

  • Publication number: 20100022745
    Abstract: A one component resin composition curable with a combination of light and heat, which comprises (1) an epoxy resin, (2) an acrylic ester monomer and/or methacrylic ester monomer, or an oligomer thereof, (3) a latent epoxy curing agent, (4) a photo radical initiator, and (5) a compound having two or more thiol groups per molecule, wherein the ingredient (5) is contained in an amount of 0.001 to 5.0 parts by weight per 100 parts by weight of this resin composition. According to the present invention, a one component resin composition curable with a combination of light and heat, which has excellent curability especially in a light-shielded area can be provided. Also, a liquid crystal sealant composition curable with a combination of light and heat, which is applicable to the one-drop-fill method and has excellent curability in light-shielded areas and adhesion reliability, especially high-temperature and high-humidity adhesion reliability, can be provided.

  • Patent number: 6424393
    Abstract: An object of the invention is to provide a high-contrast liquid crystal display apparatus which is excellent in display quality, with its substrates equally spaced with high accuracy. On a first and a second substrate are formed a color filter of three colors: red, green, and blue, electrodes for applying a voltage to a liquid crystal layer, orientation film layers for orienting liquid crystal, a pair of polarizing plates arranged in a crossed Nicol state, a TFT element, and a wire (not shown). The substrates are bonded together with spherical spacers interposed therebetween, thereby constituting the liquid crystal layer. Then, the spherical spacers are selectively placed in the color filter regions of red- and blue-color.
