PROBLEM TO BE SOLVED: To provide a hard coat film excellent in adhesion, scratch resistance and interference unevenness, a production method thereof, a polarizing plate and a display device using the same. The total acyl group substitution degree is 2.6 to 2.9, the number average molecular weight (Mn) is 80000 to 200000, and the weight average molecular weight (Mw) / number average molecular weight (Mn) is 1.4 to 3.0. On the surface where the surface plasticizer content of at least one surface of the stretched cellulose ester film having an average plasticizer content of 10 to 25% by mass is 3 to 9% by mass. An actinic radiation curable resin composition containing at least two solvents that dissolve or swell the ester is coated and dried, and then has a cured actinic radiation curable resin layer, and the boiling point difference Δbp between the at least two solvents is A hard coat film, which is a solvent at 70 to 120 ° C.
