Method of manufacturing flexible display device
First Claim
1. A method of manufacturing a flexible display device, the method comprising:
- preparing a first flexible substrate on which a display unit is formed;
forming an encapsulation unit comprising a base substrate, a second flexible substrate formed on the base substrate, and a barrier layer formed on the second flexible substrate;
combining the encapsulation unit with the display unit; and
separating the base substrate from the second flexible substrate by using a difference between a coefficient of thermal expansion of the base substrate and a coefficient of thermal expansion of the second flexible substrate, by applying a heated solution between the base substrate and the second flexible substrate.

Abstract
A method of manufacturing a flexible display device is provided. The method includes: preparing a first flexible substrate on which a display unit is formed; forming an encapsulation unit including a base substrate, a second flexible substrate formed on the base substrate, and a barrier layer formed on the second flexible substrate; combining the encapsulation unit with the display unit; and separating the base substrate from the second flexible substrate by using a difference between a coefficient of thermal expansion of the base substrate and a coefficient of thermal expansion of the second flexible substrate, by applying a heated solution between the base substrate and the second flexible substrate. The flexible display device is easily manufactured since the base substrate and the second flexible substrate, which have different coefficients of thermal expansion and are coupled to each other, are separable from each other by applying the heated solution.
