Patent ID: 7695782

Claim:
An optical laminate comprising an anti-reflection film 1 , polarizing film 2 , adhesive layer 3 , glass cell for liquid crystal display 4 , adhesive layer 5 and polarizing film 6 , laminated sequentially surface to surface, wherein the ratio (B/A) of the maximum value B of the loss tangent of the adhesive layer 5 to the maximum value A of the loss tangent of the adhesive layer 3 is 1.1 or more. and wherein the maximum value of the loss tangent means the maximum value of loss modulus (E″) storage modulus (E′)(=tan δ), each measured by heating the adhesive layer in a temperature range of −70° C. to 200° C. at a temperature rising rate of 4° C./min and a frequency of 1 Hz.
