Zusammenfassung:	A polyester single layer film according to an embodiment of the present invention has low haze and low oligomer characteristics, has a more bluish color coordinate, and has a low inorganic metal content. Accordingly, the polyester single layer film may be used as a base film of a heat-resistant protective film and a light-scattering preventive film, as well as an ITO and non-ITO base film (for Ag nanowire, or the like) used in recent touch panels. In addition, since the transmittance at a wavelength of 550 nm is relatively high due to less impurity, the polyester single layer film may be used as a base film of a prism for a backlight unit (BLU) and a diffusion sheet.
