Abstract: The present invention provides a method for improving visibility of an image display device which is capable of providing an image display device excellent in anti-reflection properties and bright-field contrast even using an optical layered body including a light-transmitting substrate having in-plane birefringence, such as a polyester film. The method of the present invention is a method for improving visibility of an image display device that has an optical layered body including a light-transmitting substrate having in-plane birefringence and an optical functional layer disposed on one surface of the substrate. The method includes the step of disposing the optical layered body such that the slow axis showing a greater refractive index of the light-transmitting substrate is in parallel with the vertical direction of a display screen of the image display device.
