Abstract: The optical laminate includes a surface protection film; a transparent support; an optically anisotropic layer; an adhesive layer; and a release film in this order, and the optically anisotropic layer is a patterned optically anisotropic layer which includes a first phase difference region and a second phase difference region differing from each other in terms of the direction of an in-plane slow axis and in which the first and second phase difference regions are alternately disposed within a plane of the optically anisotropic layer, the transparent support contains a polymer material and has a thickness of 10 μm to 59 μm, and a Δ moisture content falls within a predetermined range. The optical laminate can be stuck on a display apparatus with high accuracy and can improve a vertical viewing angle of the display apparatus after being stuck on the display apparatus.
