The present invention addresses the problem of providing a hard coating film that suppresses sliding between two films, and achieves the effect of preventing uneven winding, and providing a hard coating film that suppresses film buckling deformation and warping when wound in a roll configuration, and suppresses flatness deterioration and irregularities. Further provided are a glass scattering prevention film for an image display device using the hard coating film and having good visibility, as well as a touch panel, a polarizing plate, and a liquid crystal display device. The hard coating film according to the present invention includes a hard coating layer on at least one surface of a cellulosic ester film having a film thickness within the range of 5 to 34 μm, the hard coating film characterized in that the difference (θ Δ ) in the water contact angle of the hard coating layer before and after alkali treatment under the following conditions is within the range of 5 to 55°. (Alkali treatment conditions) Alkali solution: 2.5 mol/L, potassium hydroxide solution/treatment temperature: 50°C, treatment period: 120 sec |
