A method for evaluating optical characteristics of a transparent substrate including first and second surfaces and being positioned on a display surface side of a display device. The method includes evaluating the optical characteristics of the transparent substrate by using two index values including a quantified resolution index value of the transparent substrate and a quantified reflected-image diffusibility index value.
