1. A polyester sheet comprising 0.2 to 2.0% by weight of an ester compound, which is synthesized by using a polyvalent organic acid having three or more carboxyl groups with a benzene ring, and an aliphatic monohydric alcohol having eight or more carbon atoms, and 0.01 to 0.5% by weight of inert inorganic particles, said inorganic particles comprises a first set of inert inorganic particles and a second set of inert organic particles, the first set of inorganic particles having a first average particle diameter of 2 to 5 μm and the second set of inert inorganic particles having a second average particle diameter of 7 to 15 μm , said ester compound and said inorganic particles are blended into a polyethylene terephthalate-based polymer, wherein the polyester sheet is amorphous.
