An anti-static polyester release film according to an embodiment of the present invention is composed of a base film, an anti-static layer formed on the base film, and a release layer formed on the anti-static layer. Through the introduction of the anti-static layer, it is possible to significantly lower the peeling voltage generated during the peeling of a conventional release film, and by suppressing an increase in surface roughness of the film by making the anti-static layer ultra-thin, the anti-static polyester release film can obtain stable green sheet releasability. 본 발명의 일 실시예에 따른 대전방지 폴리에스테르 이형필름은 기재필름, 기재필름 상에 형성된 대전방지층 및 대전방지층 상에 형성된 이형층으로 구성된 것으로, 대전방지층 도입을 통해 종래의 이형필름 박리 시 발생하는 박리대전압을 대폭 낮출 수 있으며, 대전방지층의 초박막화를 통해 필름의 표도조도 상승을 억제하여 그린시트 이형성이 안정된 대전방지 폴리에스테르 이형필름을 제공할 수 있다.
