Abstract
There is provided an optical laminate that has a conductive layer directly formed on a retardation layer, is extremely thin and has an excellent antireflection function, and further, can realize excellent display characteristics even when it is applied to a bent portion of an image display apparatus. An optical laminate according to an embodiment of the present invention includes: a polarizer; a retardation layer; and a conductive layer, which is directly formed on the retardation layer. The retardation layer has an in-plane retardation Re(550) being from 100 nm to 180 nm and satisfying a relationship of Re(450)<Re(550)<Re(650), and has a glass transition temperature (Tg) of 150°C or more and an absolute value of a photoelastic coefficient of 20×10 -12 (m 2/N) or less. An angle formed between a slow axis of the retardation layer and an absorption axis of the polarizer is from 35° to 55°. FIG. 1
