1. A polyamide-imide copolymer film, comprising a copolymer resin in which a unit structure derived from TFDB (2,2′-bistrifluoromethyl-4,4′-biphenyl diamine), a unit structure derived from 6FDA (4,4′-(hexa-fluoroisopropylidene)diphthalic anhydride), a unit structure derived from BPDA (3,3′,4,4′-biph
1. A polyamide-imide copolymer film, comprising a copolymer resin in which a unit structure derived from TFDB (2,2′-bistrifluoromethyl-4,4′-biphenyl diamine), a unit structure derived from 6FDA (4,4′-(hexa-fluoroisopropylidene)diphthalic anhydride), a unit structure derived from BPDA (3,3′,4,4′-biphenyltetracarboxylic dianhydride) and a unit structure derived from TPC (terephthaloyl chloride or 1,4-benzenedicarbonyl chloride) are copolymerized. 2. The polyamide-imide copolymer film of claim 1, wherein, in the copolymer resin, the unit structures are copolymerized such that the molar ratio of the unit structure derived from TFDB: the sum of the unit structure derived from 6FDA and the unit structure derived from BPDA: the unit structure derived from TPC is 1:0.2˜0.8:0.8˜0.2. 3. The polyamide-imide copolymer film of claim 2, wherein, in the sum of the unit structure derived from 6FDA and the unit structure derived from BPDA, the molar ratio of the unit structure derived from 6FDA: the unit structure derived from BPDA is 1:0.2˜4. 4. The polyamide-imide copolymer film of claim 1, wherein the copolymer resin has a weight average molecular weight of 10,000˜400,000. 5. A method of preparing a polyamide-imide copolymer, comprising the steps of: primarily polymerizing TFDB, 6FDA and BPDA by a solution reaction to obtain a first polymer, and then secondarily polymerizing the first polymer with TPC by a solution reaction to prepare a polyamic acid solution; andimidizing the polyamic acid solution in the presence of an imidization catalyst. 6. The method of claim 5, wherein, in the step of primarily polymerizing TFDB, 6FDA and BPDA, 100 mol % of TFDB solution-reacts with X mol % of 6FDA and Y mol % of BPDA to obtain the first polymer, and, in the step of secondarily polymerizing the first polymer with TPC, the first polymer solution-reacts with 100−(X+Y) mol % of TPC (X+Y is 20˜80).
