A cellulose acylate film is stretched in the longitudinal direction by 1-300% under such conditions that the ration of the stretching distance (L) to the width (W) of the film before stretching, i.e., length/width ratio (L/W), is higher than 0.01 and lower than 0.3. The film stretched is relaxed in the longitudinal direction by 1-50% to produce a cellulose acylate film. When this film is incorporated in a liquid-crystal display, it can prevent the occurrence of color unevenness even when used in an high-temperature high-humidity atmosphere. |
