Zusammenfassung:	The present invention relates to a hard coating film for a display. The hard coating film of the present invention forms a hard coating layer having three coating layers sequentially laminated on one surface of a base film layer, wherein the three coating layers, consisting of a hard-layer of the first layer, a soft-layer of the second layer, and a hard-layer of the third layer, are sequentially laminated. Therefore, the present invention can provide a double-sided hard coating film which satisfies physical properties of surface hardness of 5 H or more and flex resistance of 3 mm or less required in a flexible display field, and is useful for front and back application of a flexible display when peeling the base film layer. 본 발명은 디스플레이용 하드코팅 필름에 관한 것이다. 본 발명의 하드코팅 필름은 기재필름층의 일면에, 3층의 코팅층이 순차적층된 하드코팅층이 형성된 것으로, 상기 3층의 코팅층이 제1층의 하드층(Hard-layer), 제2층의 소프트층(Soft-layer) 및 제3층의 하드층(Hard-layer)으로 순차적층됨으로써, 플렉시블 디스플레이 분야에서 요구되는 표면 경도 5H 이상 및 내굴곡성 3㎜ 이하의 물성을 충족하고, 상기 기재필름층을 박리할 경우 플렉시블 디스플레이 전후면 적용에 유용한 양면 하드코팅 필름을 제공할 수 있다.
