Abstract: A hard coat film has wide width and uniform and excellent surface hardness and does not easily suffer from exfoliation or cracks when the hard coat film is cut. A polarizing plate uses the hard coat film, and is employed in a liquid crystal display device. The hard coat film is obtained by arranging a hard coat layer on a cellulose acylate film. The hard coat film is characterized in that the cellulose acylate film contains elastic particles and a cellulose acetate that has a degree of substitution of acyl groups of 2.0 or more but less than 2.5, and the maximum value of tan δ (loss modulus/storage modulus) of the cellulose acylate film is 0.80-2.00 (inclusive) with respect to the film temperature from 20° C. to 200° C.
