To provide a method for manufacturing a hard coat film which has a hard coat layer and is excellent both in hardness and in prevention of curling, the hard coat film being especially excellent both in high hardness and in prevention of curling after the film is stored at a high temperature and humidity for a long period of time, a hard coat film manufactured by the manufacturing method, an antireflection films using the hard coat film, a polarizing plate using the hard coat film and the antireflection film, and an image-displaying device.

In the method for manufacturing the hard coat film having a hard coat layer, directly or via another layer, on a film base material, the film thickness of the hard coat layer is 10 m or larger, and an alkaline solution is applied onto the surface opposite to the side at which the hard coat layer is formed.
