  • Publication number: 20200172766
    Abstract: A double-sided adhesive sheet with liners includes: a double-sided adhesive sheet of which both surfaces includes adhesive faces; a first release liner that is affixed to the one adhesive face in a peelable state and includes a first release face having a low peel strength; and a second release liner that is affixed to the other adhesive face in a peelable state and includes a second release face having a higher peel strength than that of the first release face. The first release liner is arranged on a portion overlapping a part of a peripheral edge of the double-sided adhesive sheet in a two-dimensional view and includes a non-intimate contact portion that does not come into intimate contact with the one adhesive face.

  • Publication number: 20170088749
    Abstract: An adhesive member for bonding a liquid crystal panel to a protective panel that has a window frame portion on a bonding surface includes an adhesive layer, and a pair of protective sheets respectively temporarily attached to both surfaces of the adhesive layer. One of the pair of protective sheets has a temporary attachment-side protrusion formed thereon having the same shape and height dimensions as the window frame portion formed on the bonding surface of the protective panel, and the adhesive layer is arranged between the pair of protective sheets so as to conform to the shape and height dimensions of the temporary attachment-side protrusion on the protective sheet.

  • Patent number: 9389447
    Abstract: This panel composite body 1 according to the present invention is provided with: a main panel 11 that has a large first substrate 111 and a small second substrate 112, the edge portion 111a of the large substrate 111 protruding further outwards than the edge portion 112a of the small substrate 112, and that has a polarizing plate 115 arranged on the outer surface 112c side of the second substrate so as to fit on the plate surface of the second substrate 112; a plate member 12 that, protruding further outwards than the edge portion 112a of the second substrate 112, sandwiches the polarizing plate 115 together with the second substrate 112; and an adhesive layer 21 that, bonding the main panel 11 and the plate member 12, is disposed between the polarizing plate 115 and the plate member 12 and, so as to cover the edge portion of the polarizing plate 115, between the second substrate 112 and the plate member 12.

  • Publication number: 20160016396
    Abstract: A method of manufacturing a layered panel 16 includes steps of: performing a first attaching process to attach an adhesive sheet to a first panel member 110, the first panel member 110 including a panel 11 and a frame-shaped light blocking portion 14, the adhesive sheet 15 being made of ultraviolet curing adhesive and including a main body 15a and a test portion, the main body 15a being for covering a portion of a surface of the first panel member 110 that is on an inner side with respect to the light blocking portion 14, the test portion 15b extending outward from a periphery of the main body 15a and to be on the light blocking portion 14; performing a second attaching process to attach a surface of a second panel member 12 to another surface of the uncured adhesive sheet 15 such that the test portion 15b is projected outward from a periphery of the second panel member 12; applying ultraviolet rays to the adhesive sheet 15; peeling the test portion 15b from the light blocking portion 14; and checking a cure

  • Publication number: 20150068674
    Abstract: A method of manufacturing the liquid crystal display device (display device) includes: a step of coating a liquid adhesive material on at least one of opposing surfaces of a liquid crystal display panel (display panel) that displays images or a parallax barrier panel (function panel) to be stacked onto the liquid crystal display panel; a step of attaching the liquid crystal display panel to the parallax barrier panel through an adhesive material; and a step of partial curing in which an overlapping portion of the adhesive material overlapping in a plan view an outer edge portion of at least one of the liquid crystal display panel and the parallax barrier panel is cured.
