<p>PROBLEM TO BE SOLVED: To provide a polyester film which has various functional layers such as a hard coat layer formed therein, and thereby greatly reduces a haze and can be suitably used for an application to easily discriminate whether the functional layers are processed or unprocessed; and for instance, can be suitably used for a member such as a backlight unit of a liquid crystal display, a hard coat layer, a sticking prevention layer, a prism layer, a microlens layer, and a light diffusion layer.SOLUTION: A laminated polyester film has coating layers on both surfaces thereof. An absolute value of a difference between haze reduction amounts when functional layers are formed on each of the coating layers is 1.0% or more.</p> |
