Abstract(in Japanese) (See Japanese page)
Abstract(in English) A liquid crystal display has characteristics that picture quality largely changes with viewing angle. The change of picture quality is caused by changes of impairment factors for it. The color reproduction range, which was one of the factors, was picked up for a factor of the present subjective evaluation. The color reproduction range was limited by saturation of primary colors. Therefore, effects of changing saturation of primary colors on picture quality were subjectively evaluated. As the results, the picture quality was worse when the color reproduction range was narrower, in general. Saturation decrease of Blue was confirmed to have the largest influence on picture quality. Moreover, impairment of picture quality was found to be small when two or three primary colors decreased their saturation in comparison with that when one of primary colors decreased it.
