Zusammenfassung:	The present invention relates to a release film including a polyester film and a coating layer applied one or more times by a silicon release composition on at least one surface of the polyester film. The release composition comprises, with respect to 100 parts by weight of alkenyl polysiloxane, 2.5-5.0 parts by weight of hydrogen polysiloxane and 0.001-3 parts by weight of platinum-based chelate catalyst, wherein the alkenyl polysiloxane is a compound represented by a chemical formula 1, and the viscosity of 30 wt% of a toluene solution of the alkenyl polysiloxane is 1,000-8,000 mPa·s. The release film for a display device in accordance with the present invention is capable of improving quality defects caused by tearing phenomenon which may occur when separating an adhesive layer and a release film due to excellent substrate adhesion and detachment stability over time characteristics and maintaining peeling strength with a small change of the peeling strength over time. In the formula, M and N are independently an integer of one or greater. 본 발명에서는 폴리에스테르 필름과, 상기 폴리에스테르 필름의 적어도 일면에 실리콘 이형 조성물에 의해 1회 이상 도포된 도포층을 포함하는 이형필름으로서, 상기 이형 조성물은 알케닐 폴리실록산 100중량부에 대하여 하이드로겐 폴리실록산 2.5 내지 5.0 중량부 및 백금계 킬레이트 촉매 0.001~3중량부를 포함하되, 상기 알케닐 폴리실록산은 아래의 화학식 1로 표시되는 화합물이고, 상기 알케닐 폴리실록산의 30중량% 톨루엔 용액에서의 점도가 1000 내지 8,000mPaㆍs인 디스플레이 장치용 이형필름을 제공한다. 본 발명에 따르는 디스플레이장치용 이형필름은 우수한 기재 밀착성 및 경시 박리 안정 특성으로 점착층과 이형필름 박리시 발생될 수 있는 뜯김 현상에 의한 품질 불량을 개선할 수 있으며, 박리력을 유지하면서 박리력의 경시변화가 적다. [화학식 1]상기 식에서, M과 N은 각각 독립적으로 1 이상의 정수이다.
