Beschreibung
Zusammenfassung:	The present invention relates to a white polyester reflective film used for a backlight unit of a light emitting diode (LED) light source including a light guide plate in a liquid crystal display, which is capable of preventing an inorganic particle from going out and protruding to a surface, a reflective sheet using the same, and a manufacturing method thereof. According to the present invention, the white polyester reflective film comprises a reflective layer and a surface layer which is formed on at least one surface of the reflective layer and is made of a resin composition containing an inorganic particle. The surface layer includes a protrusion formed by the inorganic particle and a resin coating layer not containing the particle is formed on at least one side of the surface layer. 본 발명은 액정표시장치에서 도광판을 구비하는 엘이디 광원용 백라이트 유니트에 사용되는 백색 폴리에스테르 반사필름 및 이를 이용한 반사 시트 및 이의 제조방법에 관한 것으로서, 반사층과, 반사층의 적어도 한 면에 무기 입자를 함유하는 수지 조성물로 이루어지는 표면층을 갖는 백색 적층 폴리에스테르 필름으로서, 표면층은 무기 입자에 의해 형성된 돌기를 갖고, 표면층의 적어도 일측에 입자를 함유하지 않은 수지 도포층을 구비하는 백색 폴리에스테르 반사필름을 제공할 수 있다.
