The present invention provides a plastic film for display comprising a substrate film, an adhesive layer formed on the substrate film, a deposition film, a deposition layer, and an organic/inorganic coating layer, and having excellent adhesion properties with the deposition film and moisture and gas barrier properties by improving the adhesive layer and the organic/inorganic layer of the plastic film. The organic/inorganic coating layer comprises a silane-based compound, an acrylate-based compound, and a photopolymerization initiator for securing adhesion between an inorganic layer forming the deposition layer and a display organic layer. The organic/inorganic coating layer is photo-cured by irradiating ultraviolet rays of a specific range. The plastic film can realize a barrier characteristic of a desired level by adjusting the number of deposition films to be laminated. 본 발명은 기재필름, 상기 기재필름 상에 형성되는 접착층, 증착필름, 증착층, 유·무기 코팅층으로 구성되며, 플라스틱 필름의 접착층 및 유·무기 코팅층을 개선하여 증착필름과의 밀착력 및 수분·가스 차단성이 우수한 디스플레이용 플라스틱 필름을 제공한다. 상기 유·무기 코팅층은 증착층을 구성하는 무기물층과 디스플레이 유기물층의 밀착력을 확보하기 위한 것으로 실란계 화합물, 아크릴레이트계 화합물 및 광중합 개시제를 포함하며, 특정 범위의 자외선을 조사하여 광경화 함으로써 형성된다. 상기 플라스틱 필름은 적층되는 증착필름의 수를 조절하여 사용자가 원하는 수준의 배리어 특성을 구현할 수 있다.
