    Abstract: The present invention relates to a display film and, more particularly, to a display film comprising a substrate layer and a coating layer formed on one surface of the substrate layer, wherein a first critical radius of curvature measured in a direction in which the side surface of the coating layer becomes concave is at most about 10 mm, and a second critical radius of curvature measured in a direction in which the side surface of the substrate layer becomes concave is at most about 5 mm. The display film according to the present invention has a high surface hardness while exhibiting superior flexibility in both directions vertical to the plane direction of the film and thus is suitable for application as an outer window film for a display and particularly has the property of being applicable to a flexible display.
