An image display device excellent in antireflection performance and bright place contrast even when an optical laminate including a light-transmitting base material having a birefringence index in a plane such as a polyester film is used. Provided is a method for improving the visibility of an image display apparatus that can be obtained. A method for improving the visibility of an image display device comprising an optical laminate having an optical functional layer on one surface of a light-transmitting substrate having a birefringence index in the surface, the light-transmitting property Visual recognition of an image display device, wherein the optical laminate is arranged so that a slow axis, which is a direction in which the refractive index of the substrate is large, and a vertical direction of a display screen of the image display device are parallel to each other Improvement method.
