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 (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. 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.
