HARD COATING FILM AND FLEXIBLE DISPLAY HAVING THE SAME |
| 摘要 |
Provide are a hard coating film for a flexible display, including a transparent substrate; a first hard coating layer formed on one surface of the transparent substrate; and a second hard coating layer formed on the other surface of the transparent substrate, wherein the first hard coating layer and the second hard coating layer each have a thickness of 5 to 50 μm and satisfy a stiffness of 15 to 130 kPa·m, and a flexible display having the hard coating film. The hard coating film has high hardness and excellent flexibility. |

1. A hard coating film for a flexible display, comprising:
a transparent substrate; a first hard coating layer formed on one surface of the transparent substrate; and a second hard coating layer formed on the other surface of the transparent substrate, wherein each of the first hard coating layer and the second hard coating layer has a thickness of 5 to 50 μm and satisfies a stiffness of 15 to 130 kPa·m, which is defined by the following Equation 1:
Stiffness (kPa·m)=Compressive Elastic Modulus (GPa)×Layer Thickness (μm). [Equation 1] |
