The present invention relates to an anti-glare film, a polarizing plate including the same, and a display device. The anti-glare film includes an acrylic substrate and a coating layer positioned on at least one surface of the acrylic substrate. In a graph derived from the Raman spectroscopic analysis result of the coating layer in the thickness direction, the anti-glare film has a rate of change of a specific band area ratio. The present invention is to provide the anti-glare film with excellent mechanical properties such as excellent scratch resistance and high hardness. 본 발명은아크릴계 기재 및 상기 아크릴계 기재의 적어도 일면에 위치하는 코팅층을 포함하고, 상기 코팅층을 두께 방향으로 라만 분광 분석한 결과로부터 도출환 그래프에서, 특정 밴드 면적 비율의 변화율을 갖는 눈부심 방지 필름, 이를 포함한 편광판 및 디스플레이 장치에 관한 것이다.
