Beschreibung
Zusammenfassung:	The present invention provides an optical film and a display device including same, the optical film comprising a polymer resin which includes: a first repeating unit; a second repeating unit; a third repeating unit; and a fourth repeating unit, wherein the first repeating unit is an imide repeating unit derived from a first diamine-based compound and a dianhydride-based compound, the second repeating unit is an imide repeating unit derived from a second diamine-based compound and a dianhydride-based compound, the third repeating unit is an amide repeating unit derived from a first diamine-based compound and a dicarbonyl-based compound, and the fourth repeating unit is an amide repeating unit derived from a second diamine-based compound and a dicarbonyl-based compound. The first diamine-based compound is 2,2′-Bis(trifluoromethyl)benzidine (TFDB), the second diamine-based compound includes aromatic diamine-based compounds, and the number of amide repeating units including the third repeating unit and the fourth repeating unit is at least 80% of the total number of repeating units including the first to fourth repeating units.
