<p>An optical biaxially oriented polyester film comprised of a polyester containing polyester constituent third components other than main constituent component in a total amount of 2.0 to 10.0 mol%, which optical biaxially oriented polyester film exhibits a film haze ranging from 0 to 3.0%. This optical biaxially oriented polyester film excels in optical properties, such as transparency, low haze and optical homogeneity, and can contribute to enhancement of optical product quality and reduction of energy consumption. When the optical biaxially oriented polyester film is used as a member of LCD, PDP, organic EL, projection display, etc., there can be avoided unevenness and defects, can be realized high luminance, and can be produced high-quality images.</p> |
