Abstract:
A pressure-sensitive adhesive sheet to be used for a liquid crystal cell of a liquid crystal display, comprising:a. a base material layer formed into a light polarizing sheet or a phase difference sheet used in the liquid crystal display; andb. a pressure-sensitive adhesive layer for sticking said base material layer onto the liquid crystal cell of the liquid crystal device, said pressure-sensitive adhesive layer being constructed with a laminate body of a plurality of layers which include a first layer which is closest to the base material layer and a second layer positioned at a position closer to the liquid crystal cell than the first layer, wherein ratio of the shear elastic modulus of the second layer with respect to the shear elastic modulus of the first layer is from 5 to 99%, whereby stress which would be produced by contraction of said base material layer is relieved by the pressure-sensitive adhesive layer to prevent color unevenness or white marking from appearing on the liquid crystal display.
