Abstract
The present disclosure relates to a cover window for a flexible display device comprising: a light-transmitting substrate; and a first hard coating layer and a second hard coating layer which are formed on both sides of the light-transmitting substrate, respectively, wherein each of the first hard coating layer and the second hard coating layer has IR spectra in which a ratio of the amide C═O peak to the ester C═O peak is in a predetermined range, and a flexible display device including the cover window for a flexible display device.
Claims14
A cover window for a flexible display device comprising:
- a light-transmitting substrate, a first hard coating layer and a second hard coating layer, wherein the first hard coating layer is formed one side of the light-transmitting substrate and the second hard coating layer is formed on the other side of the light-transmitting substrate,
- wherein the first hard coating layer has IR spectra in which a ratio of an amide C═O peak to an ester C═O peak is 0.5 to 0.8, and
- wherein the second hard coating layer has IR spectra in which a ratio of an amide C═O peak to an ester C═O peak is greater than 0.8.
