<P>PROBLEM TO BE SOLVED: To provide a double-coated tape capable of fixing an LCD panel and a backlight casing, which are in a state of being held by an FPC and always applied with repulsion, to each other, having excellent drop impact resistance and repulsion resistance even though being a thin film, and further having excellent light reflecting and light shielding properties, and to provide an LCD module unit, in which components are fixed by using the double-coated tape. <P>SOLUTION: The double-coated tape 13 is used for fixing the LCD panel 20 and the backlight casing 19, which are interposed by the FPC 21 of the LCD module unit 100, to each other, and is provided with the light reflecting and light shielding properties. The double-coated tape 13 is composed of a base material, in which a light reflection surface and a light shielding surface are provided on a substrate, and adhesive layers, which are provided on both surfaces of the base material. Each of the adhesive layers has a maximum value (M<SB>1</SB>) of tangent of the loss angle (tan δ) in the temperature region between -40°C and -15°C. The double-coated tape 13 has 100 mm/hour or less peel rate in a constant load peeling strength test toward a triacetyl cellulose film and a polycarbonate plate. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
