An optical film comprising:

• an ultraviolet light absorbent having a first peak with a maximum absorption coefficient of 0.07 to 0.10 phr−1 μm−1 in a wavelength band of 290 to 320 nm and a second peak with a maximum absorption coefficient of 0.11 to 0.16 phr−1 μm−1 in a wavelength band of 330 to 400 nm;
• an acrylic resin;
• and
• a hindered amine light stabilizer (HALS);
• wherein the hindered amine light stabilizer (HALS) includes at least one of structures represented by the following Chemical Formulae A to D within the molecule:
• wherein, in Chemical Formula A, the nitrogen, and the carbon at the 4-position of the piperidine ring are bonded to other atoms within the hindered amine light stabilizer (HALS), in Chemical Formula B, the nitrogen, and the oxygen bonded to the carbon at the 4-position of the piperidine ring are bonded to other atoms within the hindered amine light stabilizer (HALS), in Chemical Formula C, the carbon at the 4-position of the piperidine ring is bonded to other atoms within the hindered amine light stabilizer (HALS), and in Chemical Formula D, the oxygen bonded to the carbon at the 4-position of the piperidine ring is bonded to other atoms within the hindered amine light stabilizer (HALS).
