    摘要： A hard coating film including a base layer including: a polymer binder resin; first inorganic particles which are dispersed in the polymer binder resin and have an average particle size of 5 nm to 70 nm; and second inorganic particles which are dispersed in the polymer binder resin and have an average particle size of 70 nm to 150 nm is provided, wherein a content of the second inorganic particles having an average particle size of 70 nm to 150 nm is 4 % by weight to 12 % by weight, and with regard to at least two of the second inorganic particles, a distance between one surface of the base layer and the center of the second inorganic particle in a direction perpendicular to one surface of the base layer is 35 nm to 5.0 µm, and the at least two second inorganic particles may be adjacent to each other in a horizontal direction to one surface of the base layer while being spaced apart by a distance of 0.1 µm to 1.5 µm.
