This study examined how the display quality of liquid crystal display (LCD) devices is assessed. A subjective experiment was conducted to identify the factors involved in quality assessments and then to determine their respective contributions to these assessments. The results are expected to drive the development of an objective quality metric dedicated to color reproduction. The subjective data were analyzed by means of a multivariate analysis of variance and a correlation study. The results showed the main effect of display on all the factors that were investigated, namely, hue, contrast, saturation, naturalness, quality, and texture. Finally, among these perceptual features, contrast and hue have been demonstrated to be the most influential on the overall quality of a displayed image.
