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, wherein the ratio (A/B) of the maximum value A of the loss tangent of the adhesive layer 3 to the maximum value B of the loss tangent of the adhesive layer 5 is 1.1 or more. The maximum value of the loss tangent means the maximum value of loss modulus (E'')/storage modulus (E') (=tan delta), 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.
