Document Type and Number:
Japanese Patent JP7368672
Kind Code:
B2
Abstract:
To provide: an adhesive sheet capable of forming a flexible display that is not only more flexible than conventional sheets but also excellent in dust resistance and resistance to improper rolling; and an adhesive sheet that can be used in applications requiring more severe flexibility, such as rollable displays, because of its superior strain suitability.SOLUTION: A pressure sensitive adhesive sheet for a flexible display has an acrylic pressure sensitive adhesive agent layer on a release agent layer of an antistatic-treated release film. The surface resistance of the release agent layer in the 23°C-50%RH atmosphere is 1×1011 Ω/sq. or less. In the release agent layer, a main component is linear silicone, and the content of branched silicone is 1 mass% or less. The acrylic pressure sensitive adhesive agent layer has a glass transition temperature of -55°C or less.SELECTED DRAWING: Figure 1
