In the present study, some factors were considered such as the various types and sizes of real Mura, and Mura inspection experience. The steps of data collection and experiments were conducted systematically from the viewpoint of human factors. From the experimental results, Mura size was the most important factor on visual contrast threshold. The purpose of this research was to objectively describe the relationships between the Mura characteristics and visual contrast thresholds. Furthermore, a domestic JND model of LCD industry was constructed. This model could be an inspection criterion for LCD industry.
