Abstract
Provided is a double coated tape with improved reworkable capability, in which a first adhesive layer, a film carrier layer, a foam carrier layer, and a second adhesive layer are sequentially stacked, and which includes a thermoplastic polyurethane (TPU) film located between the foam carrier layer and the second adhesive layer. Since the double coated tape is used for bonding of an LCD panel to a frame, while providing improved light leakage performance and reworkable capability, the double coated tape is advantageously used when manufacturing an electronic appliance such as a television, a cellular phone, and a computer.
