摘要:
A double-sided pressure-sensitive adhesive tape includes a nonwoven fabric substrate and pressure-sensitive adhesive layers present on both sides of the substrate, in which the nonwoven fabric substrate contains at least Manila hemp, has a thickness of 18 μm or less, and has a tensile strength in a machine direction of 4 N/15 mm or more. The double-sided pressure-sensitive adhesive tape is thin and is effective for the reduction in size and thickness of products to be fixed through the tape. The tape has a high strength in the machine direction and does not break during production and processing processes. In addition, the tape has a nonwoven fabric substrate and thereby excels also in punching quality. The tape is therefore particularly useful as a double-sided pressure-sensitive adhesive tape for fixing a wiring circuit board.

Disclosed is a double-coated pressure-sensitive adhesive sheet adopted to fix a hard disk drive component, which includes a pressure-sensitive adhesive unit including a plastic film base having a thickness of 20 μm or less and pressure-sensitive adhesive layers arranged on or above both sides of the plastic film base; and non-silicone release liners arranged on both surfaces of the pressure-sensitive adhesive unit. The pressure-sensitive adhesive unit has a thickness of 60 μm or less, and the double-coated pressure-sensitive adhesive sheet shows an outgassing of 1 μg/cm2 or less when the double-coated pressure-sensitive adhesive sheet is heated at a temperature of 120° C. for 10 minutes. The double-coated pressure-sensitive adhesive sheet is free from silicone, thereby causes less contamination, evolves less outgas, and is superior in workability. It has further improved followability to difference in level by controlling the thickness of the plastic film base to 13 μm or less. Additionally, it becomes resistant to “lifting” from an adherend even when subjected to a heating process after affixation, by specifying the gel fraction of the pressure-sensitive adhesive layer within a range of 10% to 60%.

A display panel device has a window, a touch panel laminate and a display panel. The touch panel laminate has: a transparent first substrate layer; a first transparent conductive layer laminated to the first substrate layer through a first undercoat layer; a transparent second substrate layer; and a second transparent conductive layer laminated to the second substrate layer through a second undercoat layer. The second conductive layer faces the first conductive layer through at least the first substrate layer and the first undercoat layer. The first conductive layer is closer to the window than the first substrate layer. A polarizing film layer is bonded to the window, and a λ/4 retardation film layer is disposed between the polarizing film layer and the touch panel laminate. The display panel is disposed on a side opposite to the window with respect to the touch panel laminate.
