According to an embodiment of the present invention, a monolayered polyester film has low haze and low oligomer properties, and has color coordinate of deep blue with low content of inorganic metal. Accordingly, the monolayered polyester film can be useful as base films for heat-resistant protective films and shatter-proof films as well as base films for ITO and non-ITO (Ag nanowires) which are currently used in touch panels. In addition, owing to low amounts of impurities, the monolayered polyester film has relatively high penetration rate at a wavelength range of 550 nm, thereby being useful as base films for diffusion sheets and prisms for back light units (BLUs).

The present invention relates to a multilayer polyester film, and a manufacturing method thereof. According to the present invention, the polyester film comprises a first polyester layer, a second polyester layer, and a third polyester layer, which are formed by being extruded and elongated at the same time by a coextrusion process. The polyester film has enhanced optical characteristics, high heat resistance, and low oligomer eluting characteristics, thereby being useful as a substrate for an ITO, a substrate for a silver nanowire, a substrate for a metal mesh, and a substrate of a prism for an LCD backlight unit.
