Aimed at the perceptual image evaluation of production appearance in product development，display model effectiveness of perceptual image evaluation between stereoscopic display and flat panel display are compared. Digital production models scored by subjects are exhibited through the two types of display usage. The reliability and validation of rating scale is checked and the inter-rater consistency is analyzed. The analysis result indicates that：as to the inter-rater consistency，no statistically significant difference can be found between the two types of display usage for evaluating the whole perceptual image of production appearance. However，subjects can reach an agreement on emotion characteristic indexes more easily in stereoscopic display environment than flat panel display.
