  A composition for a flexible substrate includes a polymer and a solvent. The polymer is selected from the polyamic acid, polyimide, and a combination thereof, and is obtained by subjecting a mixture including a tetracarboxylic dianhydride component and a diamine component to a reaction. The tetracarboxylic dianhydride component includes a bicyclic alicyclic tetracarboxylic dianhydride compound and a fluorine-containing tetracarboxylic dianhydride compound. The bicyclic alicyclic tetracarboxylic dianhydride compound is in an amount ranging from 30 mole % to 70 mole % and the fluorine-containing tetracarboxylic dianhydride compound is in an amount ranging from 30 mole % to 70 mole % based on 100 mole % of the tetracarboxylic dianhydride component.
