    Abstract: The present invention provides a plastic substrate, including: a polyimide film; a hard coating layer formed on one side of the polyimide film; and a transparent electrode layer formed on the other side of the polyimide film. The plastic substrate has excellent light transmittance high hardness characteristics, superior ITO proccessability and flexibility. Further, the plastic substrate can function as both a window film and an electrode film when it is applied to a touch screen panel. Thus, the present invention provides a touch screen panel which can be slimmed by reducing the number of laminated films including the plastic substrate.

    Abstract: Disclosed is a polyamide-imide precursor having a molecular structure in which a first polymer, derived from polymerization of a dianhydride and a diamine, and a second polymer, derived from polymerization of a diamine and an aromatic dicarbonyl compound, are copolymerized, wherein the diamine includes 3 to 50 mol % of at least one of 9,9-bis(4-aminophenyl)fluorene (FDA) and 9,9-bis(4-amino-3-fluorophenyl)fluorene (F-FDA), based on the total molar amount of the diamine. Also, a copolymerized polyamide-imide in which the polyamide-imide precursor is imidized or a copolymerized polyamide-imide film formed by an imidization reaction of the polyamide-imide precursor and an image display device including the copolymerized polyamide-imide film are provided.
