Abstract

This invention provides a composite polarizing plate comprising a polarizer, a phase difference plate, and a pressure sensitive adhesive layer. The composite polarizing plate is thin and light in weight, can ensure brightness of an image display device to which the composite polarizing plate has been applied, is less likely to cause blurred or unsharp display images, and can develop good durability. A transparent protective layer (2) is disposed on one side of a polarizer (1) formed of a polyvinyl alcohol resin film, and at least one phase difference plate (5) is stacked on the other side of the polarizer (1) through a first pressure sensitive adhesive layer (6). A second pressure sensitive adhesive layer (7) is disposed on the outer side of the phase difference plate located at a position most remote from the polarizer (1) to provide a composite polarizing plate (11). At least one layer of the first pressure sensitive adhesive layer (6), the second pressure sensitive adhesive layer (7), and pressure sensitive adhesive layers located between the first pressure sensitive adhesive layer (6) and the second pressure sensitive adhesive layer (7) contains a light diffusing agent and is formed of a light diffusive pressure sensitive adhesive layer having a storage modulus of 0.15 to 10 MPa at 23ºC. This composite polarizing plate (11) is used in combination with an image display element such as a liquid crystal cell (30) to provide an image display device.
