Abstract: A method for evaluating dispersion of a light-to-heat conversion material in a thermal transfer film includes calculating optical densities OD1 and OD2 of the thermal transfer film according to Equations 2 and 3, and calculating a dispersion evaluation value ΔOD according to Equation 1. The thermal transfer film has good dispersion of the light-to-heat conversion material when the dispersion evaluation value ΔOD is 0.1 or less, and the thermal transfer film has poor dispersion of the light-to-heat conversion material when the dispersion evaluation value ΔOD is greater than 0.1. ΔOD=|OD2−OD1| Equation 1 OD1=−log(T2/T1) Equation 2 OD2=−log(T3/T1) Equation 3

Abstract: The present invention relates to a display film and, more particularly, to a display film comprising a substrate layer and a coating layer formed on one surface of the substrate layer, wherein a first critical radius of curvature measured in a direction in which the side surface of the coating layer becomes concave is at most about 10 mm, and a second critical radius of curvature measured in a direction in which the side surface of the substrate layer becomes concave is at most about 5 mm. The display film according to the present invention has a high surface hardness while exhibiting superior flexibility in both directions vertical to the plane direction of the film and thus is suitable for application as an outer window film for a display and particularly has the property of being applicable to a flexible display.
