Abstract
The present invention is a method of evaluating optical characteristics of a transparent substrate that is disposed on a display device, wherein the optical characteristics of the transparent substrate are evaluated by selecting two values among a quantified resolution index value (T), a quantified reflection image diffusiveness index value (R), and a quantified sparkle index value of the transparent substrate. According to the present invention, a transparent substrate and an anti-glare process that is to be applied to it can be properly selected, depending on purpose and use. The present invention can be utilized, for example, for evaluating optical characteristics of a transparent substrate that is installed in various types of display devices, such as an LCD device, an OLED device, a PDP device, and a tablet type display device.
