Flexible organic light-emitting display device and method of manufacturing the same
In a flexible organic light-emitting display device and a method of manufacturing the same, a photolysis layer and an electrostaticity prevention layer are sequentially formed on a carrier substrate, a first flexible substrate is formed on the electrostaticity prevention layer, a display unit is formed on the first flexible substrate, the display unit is covered with the second flexible substrate, and light is irradiated so as to decompose the photolysis layer and to remove the carrier substrate. The formed flexible organic light-emitting display device may have improved flexibility because a flexible substrate is used instead of a typical strong and thick glass substrate. In addition, occurrence of electrostaticity during the separation of the carrier substrate is suppressed by the electrostaticity prevention layer, and thus, damage of the display unit due to electrical impacts is also reduced.
