Abstract
An image display device including a polarizer and a first optical film, in which the first optical film is arranged on a visible side from the polarizer, the first optical film has Re(589) of 3,000 nm to 30,000 nm and Rth(589) of −30,000 nm to −3,000 nm, an angle θbetween a slow axis of the first optical film and an absorption axis of the polarizer is 45°±30°, and the image display device is a liquid crystal display device including a blue or ultraviolet LED, a fluorescent body, and a liquid crystal cell, or an organic EL display device, is able to suppress the occurrence of rainbow unevenness without darkening brightness at the time of being observed by mounting polarized sunglasses, and is able to suppress the occurrence of the rainbow unevenness without darkening the brightness at the time of being observed by mounting the polarized sunglasses even in a case where a film which has great optical anisotropy and is stretched in at least a monoaxial direction is further provided on the visible side of the image display device.
