ABSTRACT:
An optical film comprising an optical base film having one surface or both surface thereof multilayers of pressure-sensitive adhesive layers, wherein the multilayers comprise a combination of pressure-sensitive adhesive layers each having a different stress relaxation time, the pressure-sensitive adhesive layer having the longest stress relaxation time is disposed at the outermost side, and the thickness thereof is 80% or less of the total thickness of the pressure-sensitive layers. The optical film is excellent in heat resistance and moisture resistance, is not difficult to cause foaming and pealing at the interface between a liquid crystal cell and the film even in using at high temperature and high moisture atmosphere, and is suitable for providing a liquid crystal display.
