The present invention is poly visibility improving method of an image display apparatus that can achieve the anti-reflection performance and spot contrast excellent image display apparatus, even when using a light-transmitting substrate on which the optical laminate having a having a birefringence in the plane, such as a polyester film It provides. To this end, the present invention is a visibility improvement method of an image display device having the optical laminate having an optical function layer on one side of the light-transmitting substrate having a birefringence in the plane, the larger direction of the refractive index of the light-transmitting substrate surface axis and the vertical direction of a display screen of an image display device in parallel so as to provide a visibility improvement method of an image displaying apparatus characterized by disposing the optical stack.
