Title:

FLEXIBLE DISPLAY DEVICE AND MANUFACTURING METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/2017/119609

Kind Code:

A1

Abstract:

A flexible display device and a manufacturing method therefor are provided. The flexible display device of the present invention comprises the steps of: forming a first polyimide-based layer by coating a polyimide-based solution on a carrier substrate; forming an oxide thin film transistor array on the first polyimide-based layer; forming a second polyimide-based layer by coating a polyimide-based solution on the oxide thin film transistor array; forming an organic light emitting diode on the second polyimide-based layer; and removing the carrier substrate, wherein the step of forming an oxide thin film transistor array can form the oxide thin film transistor array such that the oxide thin film transistor array is located between the first polyimide-based layer and the second polyimide-based layer.
