Hardened optical film having low oxygen permeability and display device including the same
By introducing fibrous or filamentous fillers into the optical film to form a tortuous path and combine it with a specific polymer matrix, the problems of low oxygen permeability and mechanical strength of the optical film are solved, resulting in an optical film with high light transmittance and low haze, suitable for the cover window of display devices.

AI Technical Summary
Existing optical films cannot simultaneously possess excellent optical properties, mechanical properties, and low oxygen permeability, thus failing to effectively protect the display elements of display devices from the effects of oxygen.
Optical films are prepared by dispersing fibrous or filamentous fillers in a light-transmitting matrix, adjusting the diameter-to-length ratio (B/A) of the fillers to 10 to 500, and forming tortuous paths in the light-transmitting matrix, and combining the light-transmitting matrix with imide or amide repeating units.
The optical film achieves low oxygen permeability, improves mechanical strength and optical properties, prevents oxygen from damaging the display elements of the display device, and maintains high light transmittance and low haze.
