Moving edge color distortion is a phenomenon that is often seen in PDP‐TVs and other displays that use a phosphor and in displays using field sequential drive. By observation using a moving picture evaluation system using a color pursuit camera, which we have developed, we were able to confirm that moving edge color distortion also occurs in LCDs. In order to clarify the cause of moving edge color distortion in an LCD, the response of the LCD was measured using a high‐speed spectrometer, and as a result, we were able to confirm that wavelength dependence of retardation is a cause of moving edge color distortion.
