Estimating the term…
There are disclosed a transparent electromagnetic wave-shielding laminate for display, the laminate comprising an electromagnetic wave-shielding layer wherein at least periphery of a terminal cross section of the layer and/or periphery of an edge thereof is covered with an electroconductive elastomer composition containing an electroconductive filler and a thermoplastic elastomer; a process for producing an electromagnetic wave-shielding laminate comprising bringing an electroconductive elastomer composition into contact with at least periphery of a terminal cross section of an electromagnetic wave-shielding layer and/or periphery of an edge of the layer, and in this state, heat press bonding the composition from a lamination direction and/or cross sectional direction to form an exposed portion on at least peripheral end of the laminate, the portion comprising the composition which is grounded to the layer; other processes for producing the same; and a display unit comprising the transparent electromagnetic wave-shielding laminate. The above laminate, which is producible in high production efficiency, is capable of following the unevenness on the electromagnetic wave-shielding laminate and on the display side grounding portion, thereby surely enabling grounding connection and electromagnetic wave-shielding.
A transparent electromagnetic wave-shielding laminate for display, said laminate comprising an electromagnetic wave-shielding layer wherein at least periphery of a terminal cross section of said layer and/or periphery of an edge of said layer is covered with an electroconductive elastomer composition containing an electroconductive filler and a thermoplastic elastomer.
A process for producing a transparent electromagnetic wave-shielding laminate for display, said process comprising bringing an electroconductive elastomer composition containing an electroconductive filler and a thermoplastic elastomer into contact with at least periphery of a terminal cross section of an electromagnetic wave-shielding layer and/or periphery of an edge of said layer, and in said state, heat-press bonding said electroconductive elastomer composition from a lamination direction and/or cross sectional direction to form an exposed portion on at least peripheral end of said laminate, said portion comprising said composition which is grounded to the electromagnetic wave-shielding layer.
A process for producing a transparent electromagnetic wave-shielding laminate for display, said process comprising applying coating of an molten or dissolved electroconductive elastomer composition containing an electroconductive filler and a thermoplastic elastomer to at least periphery of a terminal cross section of an electromagnetic wave-shielding layer and/or periphery of an edge of said layer, and cooling or drying said composition to form an exposed portion on at least peripheral end of said laminate, said portion comprising said composition which is grounded to the electromagnetic wave-shielding layer.
A process for producing a transparent electromagnetic wave-shielding laminate for display, said process comprising arranging an electroconductive elastomer composition containing an electroconductive filler and a thermoplastic elastomer on at least edge periphery of a transparent substrate of said laminate, laminating an electromagnetic wave-shielding layer so that said layer comes into contact with said composition, further laminating members of each of other layers, thereafter heat-press bonding said laminated members thereof from the lamination direction or both the lamination/cross sectional directions to form an exposed portion on at least peripheral end of said laminate, said portion comprising said composition which is grounded to the electromagnetic wave-shielding layer.
