Zusammenfassung:	A protection film for a display window according to the present invention includes a base film and an adhesive layer formed on the base film. After attaching the adhesive layer to a surface with a water contact angle of 115° or less, the peeling of 5 mm or less occurs in the bending evaluation performed after leaving the same at 60 ℃ for 72 hours. Through the same, the protection film for the display window according to the present invention has stable adhesion to the display window surface having a high water contact angle to prevent contamination, and has excellent adhesion and reliability even when being bent or crooked. 본 발명에 따른 디스플레이 윈도우용 보호필름은 기재필름 및 기재필름 상에 형성된 점착층을 포함하며, 점착층을 수접촉각 115° 이하의 표면에 부착시킨 후 60℃ 온도에서 72시간 방치 후 수행된 굴곡 평가에서 5mm 이하의 박리가 발생하는 특징을 가진다. 이를 통해, 본 발명에 따른 디스플레이 윈도우용 보호필름은 오염방지를 위해 높은 수접촉각을 가지는 디스플레이 윈도우 면에 대해 안정적인 부착력을 가져 구부리거나 휘었을 때에도 밀착성 및 신뢰성이 우수한 보호필름을 제공할 수 있다.
