Double-Sided Pressure-Sensitive Adhesive Tape For Producing Lc Displays With Light-Reflecting and Light-Absorbing Properties
A pressure-sensitive adhesive (PSA) tape, particular for producing or bonding optical liquid-crystal data displays, having two PSA layers (b, b′) and at least one carrier sheet (a), wherein the PSA tape has light-reflecting properties on both its top and bottom faces and at the same time is light-absorbing at least in so far as light not reflected is unable to penetrate the adhesive tape. The PSA tape is implemented in particular in such a way that at least between one face of the carrier sheet and the PSA layer located on that face there is a white paint layer (c). As a preference, a metallic layer (d) is provided between the carrier sheet and the white paint layer.
